qdma.com on there deer density map it looks like about 63 of 88 counties are below 15 dpsm and the other 25 counties are between 15-30 dpsm. They don't have the mtn counties like PA they have vast farmland with more than enough food but no cover to support a deer herd. The PA mtns have cover but no food. Any type of monoculture is bad for deer even if it is a 1000 acres of soybeans they will be lacking something.(cover) Thousands of acres of forest with no open areas and no timbering just can't support that many deer. All of those deer that ran around the PA mtns years ago when the hunting was "good" was because it was just coming into a closed canopy forest. There was still thick under growth plus the mast trees were starting to come into there prime. At the same time the farmlands were completely open and had no cover for deer but now old farms are grown in and there is a perfect mix of mature forest, thick over grown fields and open ag land. And that is where all of the deer are in the state now.
