If you want a taste of New York City, there is the Great Husdon River swim coming up on May 26th. Its a bit salty but not too bad. And if you want to do something BETWEEN Brooklyn/ New York City, then the swim under the Brooklyn Bridge is on July 15th. Last year I knuckle punched the stancheon on the way by and it felt rock solid. Apparently its a thrill to walk over it but personally I'm a bit queezy on heights so I prefer to go under it. So, who knows, maybe I'll bump into you in the Hudson or East Rivers this summer. I'm not sure what there is to do on the land part.
