PA took major steps to bring their deer herd in line with habitat and that has been highly controversial to many hunters that don't understand the biology behind that decision. While it is true that deer numbers are much lower than a decade ago, they are now in much better balance as far as both numbers and buck to doe ratios. I've been hunting our Potter County camp lands since the late 70s and used to see 60+ deer on opening day with maybe one being a small spike or gnarly 5 pointer (18 mo old). Now we see maybe 6 or 8 deer all day, but nearly half are bucks and some of the bucks are 3.5 and older with some nice bone up top. If you're strictly a meat hunter, you may not be happy with that.
I hunt Susquehanna County and noticed that the deer have been getting less over the past three years. I found the remains of an eight point the day before rifle season started in the area I hunt (yotes or other animal had it down to bones). Also heard from the locals to keep an eye out for suspicious activity because of they have caught two groups of poachers that were connected to the gas drilling company's. The guy's caught were fired from the gas company.
