That is really cool...
We use to go to camp Hero in Montauk Point. It is an abandoned military base at the very end of Longisland. Everything is still there such as the radar tower, the control center, a number of gun turrets and bunkers and at the north end there are the barrack and a whole small town complete with houses, a bowling alley and a bank.
Next time I am there I will take some pictures! Or you could Google Earth it :tup:
