Bnola,
Welcome to the concrete jungle. I live in NYC myself and felt compelled to answer. There is a lot of public land on Long Island that is available to hunt as well as other areas not too far from the city. Tough finding hunting partners out here in NYC, so i am more than happy to help. Heck, if you have a car, We can team up (i don't have a car - usually zipcar or borrow when going hunting). I grew up on LI, so know of some decent areas.
