The creative mind behind Build-A-Bear hopes her latest idea helps kids build something bigger—a greener St. Louis. Maxine Clark’s latest project, Trick or Tree, encourages children to collect donations on Halloween to help replant the thousands of trees lost in the devastating May tornado. The visionary hopes Trick or Tree becomes a yearly tradition, one doorstep at a time, teaching kids generosity, ecology and hometown pride.
