The community is invited to take the River Walk Tree ID Challenge and enter the raffle to win a native tree. Participants can pick up an entry at Mason Library from Earth Day through Arbor Day. Two prize winners (12 and older, 11 and younger) will be selected at the Tree Raffle Drawing at 4:45pm.As a culmination of the design plan and caring for the 80 plus trees planted on Main Street following the downtown street reconstruction, The Tree Committee and Tree Warden have documented all of the trees spanning 20 different species into a map for the public which gives each tree an address. The handouts will be available in the Library during and after the celebration.
