Unique play features, including a sway glider, we-go swing and merry-go-all, as well as a sensory-friendly rock abacus with special textures and shapes, and innovative musical stations were installed recently at Centennial Park North in Ellicott City, designed to allow anyone with physical challenges to play freely by themselves or with others.
