Fun area for boys and all those Tonka trucks and John Deere tractors. Backyard Idea, for sure!**- definitely NOT just for boys, my 4 year old daughter would absolutely love this & play in it every day we let her.
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.
