It seems to me that plenty of folks in PA that hunt private ground kill plenty of deer. As much complaining that occurs about public ground, you still hear from plenty of people that do well on it. Some of the folks that complain the loudest about hunting conditions, usually end up admitting that they did get their deer but it was not as big of a buck as they wanted, or it was a doe, or they had to hunt harder than they wanted to get it (or insert any other number of complaints here). It just doesn't sound to me like some of these folks are really enjoying themselves and they can't help themselves from wanting to take a leak on other peoples fun as well. So, yes, some folks are losing sight......
But that is why i remain a fan of the PA deer hunting discussions. Always amusing to listen to people with a freezer full of venison, horns on the wall, and living in fairly close proximity to public access hunting areas the size of small european nations but who want to bitterly complain.
