This is so outrageous that you have to read it to believe it:
From the Gothamist:
Wednesday night a few Russian women were ticketed $250 a piece for swimming past 6 p.m. at Brighton Beach. The Parks security allegedly threatened to jail them and check up on their immigration statuses. While the Parks Dept. told us that "New York State law does not allow you to swim at your own risk," the swimmers (and eyewitnesses) say that the lifeguards never alerted them that the beach was closing, and simply clocked out without getting anyone out of the water.
It's not this way in Los Angeles. You can swim anytime you want.
