 The pool for the party, because it's a concern. They even have wristbands you can put on small children. As soon as it hits water, you get a screeching alarm and also ask your babysitter if they can swim. There was another tragic case the chief was telling me about that there was a babysitter and she jumped in to save the kids, but she didn't know how to swim. So the babysitter ended up drowning.
