There's only one type of litter that's acceptable in the Metro Parks: leaf litter.

Turns out it's home to animals.

Park staff members will help visitors sort through fallen leaves in search of the critters that live there. Be prepared to get a little dirty during this Stop By Science program, set for 2-4 p.m. Oct. 22 at Battelle Darby Creek Park, 1775 Darby Creek Drive, Galloway 43119. "Looking Through Leaf Litter" is free and suitable for all ages.
