A Dry river bed instead of a traditional sand pit. Large and smaller river rock lining a sand river with tree stumps, ferns and toys. This is a home daycare that has a lot of natural play elements in their backyard play environment.
Interesting idea for putting a play area on asphalt, concrete or hard soil in a temporary build. The tires and rocks can be removed, and the sand and rocks swept up. Interesting idea for day cares in urban settings without access to grass or soil.
