Redneck swimming pool

This has nothing to do with anything, but I think its a cool idea.  Its a redneck pool, made out of tarp, hay bales and water....My girls want to make one.  Ours would be bigger, because we have large bales instead of the small squares.   http://imgur.com/a/GhWr2

Meanwhile, we had to take ours down for a couple of days, due to misquotes laying in it...yuck.  I need to mow that part of the yard anyway, so we will get it back up in a day or two.
