Query: Provides hours of fun!!

This has been, by far, one of the best purchases I have made for my kids. They play in it for hours and more importantly - TOGETHER (without fighting!!) :) I bought (4) 50 lb. bags of sand, but only ended up using 2 of them. The cover is great to keep some of the neighborhood cats from using it as a litterbox as well as from the sand getting too hot in the late afternoon. I would highly reccommend this sandbox.
