Now I REALLY Want A Pool!

I've always loved backyard swimming pools. Growing up, I spent a lot of time in eastern WA, where summer actually means "HOT" and as a result, a good percentage of homes have pools in the backyard. Luckily for me, most of my relatives are part of that good percentage. However, I now know that there is a downside to having a wonderous backyard oasis. But again, lady luck smiles on me, by providing the solution along with the problem. It appears that when you have a delightful body of water behind your house, it not only attracts all your local (and not-so-local) relatives, friends and neighbors. Yes, apparantly in addition to all those generally welcomed guests, the local pigeon population also likes to visit. But they don't want to swim. They want to foul your little slab of paradise with pigeon poop!! But now that this ingenious homeowner has shown me the way, I will fear no pigeon in my pool... When I do finally get my pool, that is.
