I complain a lot about all the time and money it takes to keep our backyard pool clean and swimmable. Let me tell you, though: The return on investment is huge during our stifling summers. Our family can't get enough of the splishing and splashing these days. It's great fun for everybody and really gives the kids a workout. When we're indoors, my offspring are usually bouncing off the walls with excess excitement, so anything we can do to burn their fuel is a good thing indeed.
