It's summertime -- the weather is hot, the shorts and flip-flops are on, the kids are out of school and if you're lucky, there's some pool time in your future. For adults, that might mean lounging on the deck with a cold beverage and a good paperback. And for the kids, it means pool games -- lots of them. Here are some family-friendly pool games that are sure to please the kids, and maybe even the 'rents as well. So grab those goggles and water wings and remember, house rules apply.
