Swimming of course is always fun, great exercise, and a great way to cool off on a hot day. I probably watched too many shark movies growing up, but when I swim in the ocean or a lake, I always wonder what is lurking in the water below me. Am alone on this?

Water is clear in a pool and you have much more peace of mind when you can see crystal blue clean. Growing up in Chicago I did my fair share of swimming in Lake Michigan as we all do now in our great state.
