Buck Magnet: That's exactly my point. The habitat/food is missing in the northern PA, and it won't get up to potential until the deer density is FIRST lowered so that the food can get ahead of the deer. You can't "build-up" the food supply, you need to take the deer density down to the point where some food gets past the deer. Then you can begin to build up the deer herd again but never back to the levels it was in years past.
Where I hunt in Berks is like you describe in Indiana co.
