This seems like an obvious one. You can take a party bus service to the beach, the lake, pool parties, lounge-beside-the-pool-parties that become pool parties as soon as some unwilling victim gets tossed in. It’s all fun and games until someone partially clothed and holding a beer gets thrown into the pool. Then it’s even better, obviously. At adult pool parties (and by that I just mean pool parties that happen to be for adults, not, like adult adult pool parties), sometimes it takes someone getting shoved in the water for people to actually use the pool properly. Sure, people are floating on floaty things, drinks in hand, chatting to the people on the floaty things next to them, but that’s not really swimming.
