Warm days are here, and what better way to beat the heat than with a dip in a cool, refreshing swimming pool? No pool of your own? Luckily, you can easily and affordably join a local community pool. Or you can really get off the beaten path by seeking out a more natural swimming hole. If, however, you prefer more sun but less adventure with your swims, go ahead and get soaked this summer at one of these 50 outdoor municipal pools, one in each state.
