David Pfeiffer, Director of the museum, says the Dec-A-Tree event kicks off the season November 24 and runs through December 30. Fifteen nonprofit organizations, such as booster clubs and other less prominent groups, start decorating their trees November 19. Their goal is to bring awareness to their organization as they help create a snowy, enchanting Christmas scene with their decorated tree along a winding path. For a holiday visual sensation, stroll through this second-floor display during the museum’s open hours, Tuesday-Friday 9 a.m.-4 p.m. and Saturday 10 a.m.-3 p.m.
