Critters and Creepy Crawlies – What’s in the dirt? Under that rock? Fresh Air Family naturalist Carl Sloan leads pre-school children and their families on a discovery hike looking for all that crawls or creeps just beneath the soil. Roly ponies, slimy salamanders, worms and bugs can all be found along the Vulcan Kiwanis Trail. A partnership with Vulcan Park and Museum.
