We always talk about my Prosser pastures on the show and keeping them green -- then I discovered this video online, thanks to my wife. The pool looks dirty, but it really isn't and you can build this yourself with easy-to-get materials.

I thought the water looked nasty, but it really is clean and safe. And when you look closer you see the pump. You can actually build this right in your pasture in the Yakima Valley and it will keep you cool for the rest of the summer.
