Though all lawyers have mentioned, I tend to agree that if your children are swimming at the pool they need to be supervised by you (the parent or another responsible adult who assumes responsibility.) In all actuality I think this will very soon cut down on the number of "pool visitors," as parents may not be willing to spend the time supervising their children. These owners are paying dearly for the supervision of their children in this part of PA., An expense not shared by those in the neighborhood to say it as gently as possible.
