Rockaway Beach? That's sort of a special case I think.
It's very accessible by a lot of poor inner-city kids who can't swim. They've run around and splashed in 3 foot or so pools but can't swim, have no concept of ocean safety, don't have friends or family that do and if they've got a good muscle to fat ratio they sink like rocks. I hear of a kid drowning at Rockaway beach or inlet on the news almost every other weekend and I don't listen to the local news all that much. School trip - no lifeguard - kids go in the water - kid swept away, random group of kids wading, one gets swept away, over and over.
