This 30 ECTS thesis is the final project of the Landscape Architecture Master programme with the Urban Design specialization at the University of Copenhagen, Faculty of Science.

Towards an attractive city: Tønsberg argues for a development of a dense city with recreational public space in a middle-sized city in Norway. By using the opportunities created by industries on the threshold of moving out, the project proposes a development of the canalscape as the carrying landscape element for a strengthened city centre.

I want to thank my supervisor Peter Lundsgaard Hansen for supervision, critique and inspiration.

Thanks to Nina Ambro Knutsen, Øyvind Søfteland and Turid Vongraven at the Norwegian Public Road Administration for sharing their knowledge about Tønsberg and providing GIS material. Thanks Tønsberg municipality for discussion and maps. Thank you Oskar, Jens and Leonor, for great feed back sessions and proofreading.

SAMMENDRAG

Over ett strekke på 2,5 km langs kanalen i Tønsberg, Vestfold, fra Danholmen i nordvest til Stensarmen i sørøst, ligger flere store industriområder sentralt beliggende i forhold til Tønsberg sentrum. Kanallandskapet har siden industrialiseringen blitt dominert av storskala industri og logistikk. Industriene er i dag på terskelen til å flytte, og åpner muligheten til en nytenkning av Tønsberg sentrum.

Dette prosjektet foreslår en strategisk plan for utviklingen av sentrum mot en mer attraktiv by, hvor kanalen brukes som det bærende landskapselement. Ved å utnytte potensialet langs kanalen, fremmer forslaget en sammenhengende rekreativt bylandskap for mennesker som grunnlaget for bysenterets utvikling. Det er fokusert på god tilgjengelighet, sammenheng og opphold for gående og syklende, gjenbruk og isenesetting av ikoniske bygninger som ledd i Tønsberg industrielle kulturarv og å bruke utviklingen av kanallandskapet som katalysator for sentrumsutviklingen.

Samtidig er Tønsberg en del av Oslofjordregionens store vekst. 20 000 nye innbyggere er beregnet til å flytte til Tønsbergregionen de neste 25 år (Tønsberg Kommune, 2014). Manglende areal til utbygging av nye boligområder i kommunen og den brede politisk vilje for sentrumsutvikling gjør industriområdene naturlige lokasjoner å se mot.

Along the edge of Tønsberg canal, Norway, is a large industrial areas in the close proximity to Tønsberg city centre, spanning 2,5 km from Stensarmen in southeast to Danholmen in northwest. The canal landscape has since the industrialisation been dominated by large-scale industry and logistics. Several of the companies are on the threshold of closing or moving abroad, leaving large sites central to the historical centre

This project proposes a master plan design for the development towards an attractive bicycle city by using the canal as the carrying landscape element. By using potential sites along Tønsberg canal, the proposal aims at a coherent urban recreational canalscape for people, as the base for future growth. In the design, the focus is on public access to and along the canal, to reuse the existing industrial buildings as cultural heritage

open for discussion.

as well as giving identity to the new districts, and use the new canal landscape as a catalyst for urban development.

At the same time, Tønsberg is a part of the Oslo fjord region facing a large population growth.

Within the next 25 years, the city is expected to grow by approximately 20 000 people (Tønsberg Kommune, 2014). Having no more available sites for the classical residential areas and a new political will of developing the city centre, the centrally industrial sites are evident locations to carry out the transformation.

INTRODUCTION

Tønsberg is a middle sized city in southern Norway, located in the inner Oslo fjord. The city is awaiting a large population growth at the same time as central industries are moving abroad.

This creates a potential of an attractive accessible canal landscape using urban space as the driver in strengthening the city centre.

by TNS gallup in 2014 showed that in the 13 biggest cities in Norway, the majority of the population would like the municipalities to focus on livability and attractive city centres (Bypakke Tønsberg regionen, 2016).

Another aspect in Tønsberg development is the car dependency. The city centre is small, and very few people live here. The majority lives in the

The sprawl of single family house residential areas have taken up the majority of the hinterland, which is not agriculture-, nature- or recreational areas protected by law. This means the development has to take place in existing city structure (Tønsberg Kommune 1995). This creates the potential of an urban development through transformation and densification of Tønsberg’s central areas.

residential areas around the city, driving into the centre for work and shopping. The last 30 years of development has established large shopping and offices at the periphery of the centre, decreasing the number of every-day users of the city centre.

Today, there is a political and public wish for a more environmental friendly means of transport, where electrical bicycles and cars are more and more frequent in the townscape.

In Norwegian tradition, the recreational outdoor life is strong. People enjoy skiing, bicycling, With this background, the potential for walking and just being in nature. The weekends developing the canalscape both as a new public are spent in the cabin, in a boat or a stroll in the space and a development of the city centre sets nearby countryside. The use of urban recreation is the premise for the development of Tønsberg. It less utilized. Urban life is something experienced provides attractive public space to an increased on weekend trips to Oslo, Copenhagen and other number of people living and working in the city big European cities. However, there has been an centre. increased interest in urban qualities in the cities in Norway the last few years. A survey conducted

The cityscape is a mnemonic device for memory (Herrington, 2009). The industrial areas that are closing can be seen as more than mere potential development sites, but as potential new cultural heritage, giving the places meaning (Braae, 2015).

The sites suggested opened and developed into public realms in this thesis adds to Tønsbergs ability to convey its industrial history, a new layer in the city’s history as trade centre and historical town.

The idea of this thesis originates in a wish for The central part of the city is small, consisting of a more bicycle friendly city. In the preliminary a dense historical town with culture, restaurants work preparing for the thesis I investigated and shops. As a doughnut surrounding the city the present conditions of the bicycle network, core, large-scale shopping and office complexes concluding that the network was great in the are established along the main infrastructure countryside, and terrible in the city centre. arteries. In the combination with the majority Therefore the start of the thesis work focused on of inhabitants living in single-family houses in improving and implementing bicycle lanes of the residential areas outside the city and abundant city centre. parking possibilities throughout the city, the car ends up being the most convenient means of In the process of understanding the bicycleability transport in a hectic everyday life. The utilisation of a city, I asked myself why the bicycleability of of the populated areas leaves a density at 1923 Tønsberg is so poor. It does have great potential, persons/sq-km. As a result, there is not enough located in a region where 70% lies below 150 people to support an active urban city for the m above sea level and in Norwegian context has reach of the city. Such a structure does not mild winters. In addition, the main residential encourage people to take the bicycle. If there areas lie within 7 km from the city centre, with is not something to bicycle to, bicycle lanes are a total ascent of maximum 60 m. Out of 80 irrelevant. The bicycleability is not down to one 000 inhabitants in the Tønsberg region, 25 000 dimension, the transport infrastructure itself, it is can bike to the main square in 15 minutes, and a much broader, complex issue.

40 000 can reach the square in 20-25 minutes (Bypakka Tønsbergregionen, 2016).

Based on these factors, the project focus became to look at a way to strengthen the city centre, The first hypothesis of why the bicycleability is by making the city a more attractive place for so bad was that there is so few and poor bike- everyday life. Places that people spend time lanes, leaving no space for the bicyclist in the outdoors in the public space because they are streetscape. This is a part of the story, however, inviting and interesting to be in. the main reason I found was the structure of the city.

Problem

How can the development of recreational public space act as a driver for an attractive lively city?

The city centre does not have enough public space or inhabitants to make it an attractive city.

There is a discord between the reality of the city and the envision of the city. Tønsberg’s sprawl and development of larger road network and car based shopping can be described as an outward development. To increase its attractiveness, it needs to look back towards its city centre and strengthen it.

The problem is that the urban life people want does not have the premises in the city structure as it is today.

•

There is not enough urban qualities to make the centre interesting for people.

• •

People drive to all destinations.

People live in the outskirts and not enough use the city centre in the everyday life.

There is a need for variation in the public spaces, not only cafés, shops and streets.

There is a lack of recreational urban spaces.

The canal acts as a barrier between the residential areas and the city centre.

The use of urban space for a city to be attractive: 1, a lively city that has during the 20th century shifted from being encourages people to walk, bicycle and stay in dominated by necessity, such as work related the public space. 2, a safe city where there is a activities to a domination of optional activities coherence in the city structure, short walkable (Gehl, Gemzøe, Kirknæs, Søndergaard, 2006). distances and mixed functions. 3, a sustainable This shift is a consequence of the movement city where means of transport has low emissions of functions such as trade, news and transport and 4: a healthy city where activity is a part of indoor (Gehl et al., 2006).

Registration, analysis and investigation

Design by references Design by models Design by drawing Design as we speak Repeat

In the design process from idea to plan, I have worked with hand drawn sketches, collages, model making and digital drawing. In the initial stage, a reference collage was used to identify sites and imagine possibilities. The references was translated into a model, creating a discussion reflecting the decisions being made. The model was transferred to a digital drawing, where new issues came up. This process was done over and over again, to mould the idea. Parallel to this

process, inputs came from my supervisor and my fellow thesis students, and research, analysis and investigation of the city was conducted.

As I have worked alone, dialogue created between model and drawing has been important for me.

The process of analysis, decision-making and site definitions can be illustrated by Burn’s and Kahn’s theory of site (2005).

In this framework, the analysis is divided into the area of effect; in this project understood as the city of Tønsberg, the area of influence as the canalscape and the area of control being the three sites Danholmen, Ollebukta and Stensarmen.

Tønsberg in a regional context Tønsberg is a part of the Oslofjord region, the fastest growing region in Norway. Oslo is the fastest growing capital in Europe (Juven, Mikalsen, 2015). For the last decade, policy makers have focused on flerkjernet utvikling (multiple core development), to both strengthen the largest cities/city-clusters in the region, as well as relieve some of the pressure on Oslo (Osloregionens styre, 2016). Tønsberg is one of the cores in this strategy. Several people commute to Oslo for work, while they enjoy living in a single-family

house for the same price as an apartment in Oslo.

The development of an InterCity train gives both opportunities for a larger labour market and more competitive cities in the region, however, to avoid an increase in commuters and long commutes to Oslo, it is important that the cities in the region are attractive for creation of new jobs and settlement (Osloregionens styre, 2016).

The regional terrain The landscape is characterized by a hilly terrain inland, gently sloping pastures and farmland and a coast landscape with scattered islands.

Tønsberg’s location is defined by the landscape’s premises. The city lies protected in a side fjord of

the Oslofjord, where the shore enabled building a harbour. The site is protected from wind and stormy ocean by the islands surrounding it, and access to a fertile farm and forest hinterland.

On-going processes

The central part of Tønsberg is undergoing several development projects, including, but not limited to: •

•

Two studies has been carried out: potentials in Nedre Langgate and the canal by Dyrvik arkitekter and PlanUrban.

The expected population growth, lack of areas for housing development, industry moving out and a wish for a sustainable urban development has opened up for a bold vision for the city centre, and opens up to rework the city centre instead of expanding the city.

Summary

The analysis of the city depicts a middle-sized city with seemingly endless single family house areas and car-based shopping areas. In the light of the desired development of the city towards an attractive city, it has become clear that the city centre needs to be strengthened and expanded, with housing and public spaces.

Looking at inherent landscape qualities and possible sites, the canal is an overtly potential for the development.

Summary

The analysis of the canal reveals great variation along the canal as there are several districts with different characters and functions. The city centre is already well connected to the canal and has a few public destinations on both sides with the majority clustered around the city centre. The accessibility is poor at the canal front as large areas are occupied by industry, Nedre Langgate acts as a barrier between the city and the canal

as well as the residential areas at Nøtterøy, and hence can work as a linking element between them, decreasing distances for bicyclists and pedestrians. The timing is right, as the majority of the industries are on closing or moving out.

The sites hold several characteristic buildings and elements that can covey the city’s industrial history as mnemonic elements in a new cityscape.

southeast of the city centre and the lack of bridges across the canal disjoint the city centre from its adjoining residential areas.

In total the analysis of the canal encourages a further development of the canal.

Industrial sites along the canal offers great potential for the city centre development, as they are in close proximity to the city centre

The three marked sites have the potential to expand and connect the city centre and the adjoining residential areas.

The sites covers a total of approximately 364 000 sqm, a huge area compared to the city centre of approximately 195 000 sqm.

The current city centre is interetingly comparable to two of the sites; Stensarmen and Danholmen.

This can give locals an idea of how much more the city centre can be.

Comparing the sites size to other known areas gives an impression of how much they can contain. It does not mean that they should be exploited in the same manner as the compared sites.

Danholmen

Danholmen is located in the northwest part of the canal and has been an important part of the city’s industrial history and skyline. The industrial site is the remaining part of Kaldnes Mekaniske verksted, established in 1899, that closed in the 1980’s and from then until today has produced components for the oil rigs. Currently, the landowner wish to open the area for urban development.

characterize the area. There is poor vegetation on site, consisting of some wild grown vegetation and a lawn in the southern part of the site, by the temporary studios, and some wild growing shrubs along the waterfront. The ground cover is gravel.

The site is fenced off with the only entrance through a gate at Stalsbergveien. Iron structures within the site fills up the in between spaces and creates an internal infrastructure.

Ollebukta is the city centre’s main marina for private small boats. It is located just south of the city centre, connected by a path from Oseberg hotel and conference centre. In the past, the marina and the area behind have been a logistic site. The marina got a makeover in 1999, as a part of a bicycle network program for Nøtterøy and Tønsberg (Miljøverndepartementet, 1999) and a promenade and bicycle path was added. The areas

In the southern part of the marnia there are two buildings for the boat club, a crane and a gas dock. In the northern part is the city’s fire station, a second hand shop, a bed shop and a gas station. Between these two areas is a strip that is used for parking and a road taking you down to the clubhouses. During winter, the space is used to store the boats on land.

behind are mainly used for parking and largescale shopping.

There is a row of Alnus glutinosa along the promenade and Acer platanoides along Nedre Langgate. The green space between the clubhouse and FV 308 has large old Aesculus hippocastanum and some Acer platanoides.

The promenade is connected to the main strip ‘Brygga’ by Oseberg hotel and conference centre in the north, and to the canal bridge in the south.

Access by car is through Nedre Langgate. Nedre Langgate acts as a barrier between the marina and the park and residential area behind.

Stensarmen is located at the southeastern tip of the canal. After 1945, the port authority constructed the area. The area is defined by the canal in the west, the FV 308 in the north, the Ringroad in the east, and Presterødkilen wetland reserve in the south. The waterfront is fenced off as an industrial site for Norbetong producing concrete and the port authority.

Vision and proposal

85

Prelude

The following pages depict through text, plans, visualisations, sections and diagrams the proposal for a strategical development of Tønsberg city central areas. A fundamental premise for the plan is the way urban space is utilized as a driver for the development, conveying the industrial history by putting characteristic buildings and elements along the canal into play and create a connected coherency for pedestrians and bicyclists. Through transformation and densification, the fundament is set for an attractive city centre for people.

V i s i o n s f o r th e c it y

To be a 24 hr city for work and leisure

Connect residential areas and city

Increase residents in city centre

Stimulate green mobility

The three sites have great potential to strengthen the city centre by creating new districts that increase number of inhabitants in the city centre, connects the existing residential areas and the

city, encouraging green mobility and offer both urban and recreative spaces for the city to live 24/7.

88

Str ate gy f o r th e c a n a l

Open up the canal landscape

Link existing promenades to a coherent canal promenade

Act as catalyst for development

Re-use existing structures as identity-makers

Combined, the three sites and the existing promenades opens up the canal landscape and create a coherent canal promenade. Each new district is focused around characteristic elements and buildings, which both gives the district

identity and tells the industrial story of the pace.

As the new public space is established, it works as a catalyst in the development of the district and the canalscape.

89

Th e c o n c e p t

urban development

street

promenade

The main concept is to let pedestrians and bicyclists access the waterfront. Along the canal, a promenade connects in various ways to the water, and to different sites. Parallel to it, a bicycle path makes an efficient and beautiful connection to the points of interest. The destinations are centrered around the characteristic elements of each site, in order to stage the industrial elements to convey their history.

Sitting

Bridges

canal

The recreational urban space along the canal is defined by the promenade by the canal front and the row of trees creating its backbone. Behind the rows of trees, the districts are allowed to develop.

New bridges are essential to put the new districts to play, to connect existing residential areas as well as to encourage bicyclists and pedestrians to use both sides of the canal, creating multiple routes with in total four crossovers.

Danholmen

At Danholmen, a new central district starts to develop. This site has the potential to set the stage for a large public space, staging the former industrial buildings and framed by the existing quay. The quays at the canal front are taking part as new promenades, linked to the existing promenades at Kaldnes brygge and into a new urban forest at Danholmen headland.

The new urban space is put to play by a new bicycle and pedestrian bridge connecting Danholmen and the northwestern part of Nøtterøy to the city centre.

Behind, a new infrastructure of trees establishes a structure for the new district to form. The stream is reopened and runs along the main entry to the area from Ramdalsveien.

The two main buildings on the site are suggested to be reused as public buildings, for example as a climbing facility, a school or an event building.

By giving the former industrial buildings a public funtion, the district is given identity and tellts the sites industrial story. The area in front of the buildings creates a large open space, a new venue towards the canal-front.

Ollebukta is transformed into a new active urban space and works as a green link between the city centre and Stensarmen. The current parking lots between Nedre Langgate and the promenade by the marina are converted into an activity strip with bbq area, volleyball, petanques courts, swings and play areas. In the winter, the space is still usable for storing boats on land, as all interventions happens on the ground or as

the street as far north as possible, it opens up more space for activity in Ollebukta. Parking along the street protects the bike lane from traffic, as well as making Ollebukta accessible for those arriving by car. Less traffic and more trees gives the street a softer look, and instead of being a barrier, it connects the city and Ollebukta through four entrances, one for cars and four for soft traffic.

structures across site to ease the organization of boats.

As the traffic at the road running along the promenade to the clubhouse is low, it is converted into a shared space. This allows the activity strip and the existing promenade to merge to one large urban space.

Nedre Langgate is part of a larger transformation, as it is planned to be a one-way bus boulevard with bicycle lanes and sidewalks. By organizing

Stensarmen becomes the counterpart to Danholmen on the south-western bank of the canal. Promenades and bicycle paths are giving access to the waterfront, and a new bridge connects to Ă˜rsnes brygge and residential areas in proximity.

At Betongplassen, the former concrete industry ground, the concrete conveyor is a remaining element, creating an arch for bicyclists and pedestrians to walk through. Here, a skate and scooter area is established and a food truck square offers street food.

Along the promenade, there is access to the water as a lowered wooden dock, a new harbour bath,

Concrete is used for stairs, squares and some main paths. Corten steel is used for details and slabs at Boreplassen, and yellow-coated ladders for safety and swimmers are inspired by industrial elements that are present today.

Wood is used as a contrast to the hard concrete, at benches, docks and pontoons. Trees provide structure and shade, as well as being beautiful to look at. They are also essential for a sustainable city by the helth benefits people receive through urban greening, trees importance for biodiversity and the ecosystem services they hold.

Lawns and meadows invites for play and relaxation. Hedges create a visual element in the middle layer, and help define spatial sequences.

The sound of walking on gravel and the softer look gives a more relaxed expression. Gravel is used at the paths running through the forest area at Danholmen and Stensarmen.

Salix alba ‘Sericea’

Acer platanoides KORSA ® E Spisslønn

Alnus glutinosa

Sorbus ‘Dodong’

Betula pubescens

Quercus petraea

The vegetation volume is planted after two strategies: the precise rows of trees and the free forest vegetation. The rows of trees are running parallel to the canal, emphasising the main streets and paths. The streets are cohesive entities of monocultures, however, each row is a different

Ulmus x VADA ® Resistent Alm

Prunus x yedoensis

species, fitted for the specific street, giving the whole a variety. At specific places as where the bridges land and at entrances, a grid of trees with seasonal qualities adds to the experience.

126

Salix x sepulcralis

Alnus glutinosa

Fraxinus exelsior

The forest plantations are floating through the sites, creating an overall green lush space. As large parts of the sites are former industrial areas with heavy machinery, and have high water levels and are exposed to sea salt, a vegetation mix adapted to these conditions are necessary. A vegetation type of Fraxinus excelsior and Alnus glutinosa with a mixture of Quercus robur, Tilia cordata, Acer platanoides and Betula pubescens is both custom to the growth conditions and are native to Norway. The understory is a marmoration

Sambucus nigra

of Corylus avellana, Sambucus nigra and Prunus cerasus, creating a local “100 m forest� for the children to play. Along the opened stream and at the entering point of pontoons, Salix x sepulcralis are planted.

All species are native to Norway or registered as low risk as invasive species at Artsdatabankens list of invasive species from 2012.

Phases

To secure the public spaces in the development and make it flexible to accommodate for uncertanties, the implementation is organised in phases. The most important structures should be established first. Access is crucial for the areas, as they have been inaccessible sites for a century, it is a dead end and a blind spot in the populations image of the city. By providing access, the area opens up for exploration of the sites, temporary

Phase 3 continues the urban areas development.

The districts establish and become integrated parts of the larger urban city centre of Tønsberg.

The sites should be constructed and established to follow the growth for the next 25 years and use the expected population growth as fuel for the development.

interventions and events. Phase 1 hence comprise the promenades and bridges, forest vegetation at Danholmen headland and Stensarmen park, re-opening of stream at Danholmen, as well as the landing-place for the bridges. This phase is estimated for a 2-8 year period.

phase 1 and starts to develop in phase 2, a phase n is occurring, where the development of the sites acts as a catalyst for further development of the canalscape. The development goes beyond the stipulated sites in this proposal, as it has an influence on the larger development in the city, focusing it on the area around the canal and hence influences the dynamics of the city. The result is more people in the city centre, inhabiting the urban space, creating a positive activity spiral, where the activity generates activity.

Phase 2 is about structuring the area. The rows of trees are established, smaller path-networks ads a more fine-masked infrastructure pattern.

Boreplassen at Danholmen with lawns, stairs, pavement, hedges and trees opens the new venue at the canal front. The harbour bath at Stensarmen creates a destination for people to visit. The aim is to establish the public space and let the people inhabit them, and in that way secure them from being built down by residential blocks all the way to the waterfront, as has happened at Ă˜rsnes and Kaldnes brygge. A new district in shape of block structure emerges in the structure of the trees at Danholmen. Phase 2 is estimated to cover a 5-10 year period.

Phase n: After the sites have been accessible in

The phases might take shorter or longer time, and they might overlap in some extent. There are many uncertainties for the development, as the date for the sites to become available is still unknown. However, the idea is that a strategy for the city’s development and a concept for the sites shall be ready when the sites opens up, and that the principles of access and public spaces are implemented.

128

Phase 1

Access is established. Fences opened, buildings torn down, the stream is reopened and the two bridges are built.

Phase 2

The rows of trees, as the main structuring elements are in place. Danholmen developes as a new neighbourhood.

Phase 3

The vegetation establishes. Stensarmen starts developing.

A more attractive city is a city where people are given room to inhabit the space between the buildings just as much as the buildings themselves. The potentials along the canal can accommodate this, with the large common room that the waterscape gives.

By working with the city, initially to enhance the bicycleability, I have realised that a bicycle city is a part of the fundaments of being an attractive city, but cannot exist by on its own. The attractive city is a prerequisite for a bicycle city.

Towards an attractive city; Tønsberg utilizes urban space as the driver for the city’s development, that way securing access and defining the public spaces. Through a holistic approach, the sites were identified, and seen as potentials to create a greater coherent city. By understanding the site as area of control, influence and effect, the strategy reaches beyond the stipulated areas of this project, and influences the dynamics of the city, giving the city centre momentum in the process towards an attractive city.

Scanrope is still a barrier in a coherent canalscape, and is with its location a keystone in a coherent canalscape in Tønsberg. The day the site becomes available, it will naturally follow into the greater canalscape in Tønsberg and let the industrial site make way for new districts with future businesses to prosper.

By inviting people out in the urban space, the city comes to life. City life emerges when people inhabit the urban space and make it a part of their every day life by using it for activities such as to walk, stay, sit, stand, look at others, enjoy the weather, go for an afternoon run, sit in the grass, meet friends or just read the paper. Activity levels in cities increase as a consequence of selfreinforcing processes. Activity breeds activity, and city life needs space.

Something happens because something happens because something happens.

The process of this thesis has made me aware of my own working habits. Throughout my education, I have been working in groups the majority of the time, where through dialogue create the project together, and produce its content.

For this thesis, I have been alone in producing the physical product, nevertheless, the content is an outcome of a continuous dialogue with my supervisor, fellow thesis students, work in different media, variation from physical models, scales, diagrams, digital drawing and visualisations. This process has to me underpinned the importance of dialogue and discussion in the design process.

131

From this process I find it overtly stimulating to work in groups, where a collective rolling dialogue is brought to the table. Speaking is to me a way of expression, a way of defining a project, a way of making decisions and a way of challenging the project. Therefore it is the open dialogue that is the crucial part of the design process.

It has been an enriching process and I have enjoyed it even though it has been though at times. It is interesting to see how exploration of a theme can unveil layers I did not anticipate. The result is beyond what I pictured when I started this project. I am happy to finally have it in print.
