There are areas which are extremely steep and areas which are are too far to be accessed from roads. My son lives in the suburbs of Pittsburgh and has a 10 point buck which rubs on a tree in his front yard next to his steps, car and main road. There is no hunting near that area and the buck has been a 10 point for at least 3 years.
You are kidding yourself if you think no one is sneaking into and hunting any little patch of woods that they can around Pittsburgh. I know people that hunt in some RIDICULOUSLY tight places.
