I had the same thing happen, but now I hunt in Delaware County. The land is much less crowded and there is much more land up there. Try hunting the watershed lands that NYC and the DEP have opened to hunters. There is about 36,000 acres open in many different parcels. I hunt it all the time and it is great. Go to this website for info.

Hope this helps!
