Thanks, Ann. You mean, there's Fake News on Yo!Rube! as well as the tv kind?
Anyway, I'm betting the guy is just a poseur, calling himself a New Yorker but not at all a native. We get lots of tourists, some stay for years, and they're still just *tourists* cluttering the place up.
Kids have drowned swimming in the Hell Gate (just north of that launching site), I knew one long term tourist (who since retired elsewhere) who
lost a son that way, probably 40 years ago.
Most of the natives would tell you, swimming or paddling in the East River is about as appealing as taking a bath in a Waring blender. And, under widely known city law, it is also illegal to walk across the
water. That tends to start religions and cause other problems, too.
