Back yard beach

It's way too cold for a trip to the "local lake" that is almost two hours away so today while it was above 50 we took the opportunity to get out our sand box. For safety reasons we opted to not get a big box to leave out. Instead we got a shallow storage tub that goes under the bed and put part of a 50 pound bag of sand in it. Daphne loves it! Her cars go on trips, she builds castles, she can even grow fake flowers in them. So many things a girl can do in the sand! On a side note I'm contemplating getting a cheap hard plastic kiddy pool to put under the swing set slide to make a water slide. Has anyone tried this before? If you have let me know how it went!
