Dick..I am from Lower NY (orange/westchester county) and I havent found any decent trails in this area. If you are in NY and you want to go wheelin you at least have to hit sullivan/dutchess county. Thats approx 2 hours from you...just to get started..

I know a decent place in Elmhurst (Queens) on Queens Blvd going towards the 58th st bridge. Its next to a Mcdonalds..they sell some 4 wheel stuff there..the name slips my mind though.

Welcome
