Enchanted Woods - Winterthur Museum, Garden and Library in Delaware. there's a huge beautiful garden, and a whole enchanted woods with little wooden faerie houses and messages from the fae snuck in places.
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.
This is a wonderful item for a children's play yard. I can see a water pump on one side that empties into a trough and then moves to the waterwheel. The water can seep though the rocks and into a catch basin which can recycle the water back to the pump.
