Every state is controlled by how many deer they have and how many hunters are buying licenses.
Pa has the most hunters; thus it has to control things a little tighter than other states. It has a fine system of public hunting lands, State Game lands, State forests, and a National park in the western part of the state. Most unexplored by those who would get lost. The batteries die on the gps and they aare dead meat.
Back in the 70's Pa went from one deer per hunter to one deer per season with the addition of a late season flintlock muzzleloading season. With so many hunters, Pa had to go easy.

Now its any kind of single shot muzzleloading rifle including kinds never invented before, plus the single shot bows and single shot crossbows that look more like modern military firearms.
And still hunters are looking for semi-auto firearms; a hunter needs all the advantage he can get.

That's the thing. Get the newbies and the inaccurate to a place where they too can harvest a deer. Its forbidden I guess not to harvest a deer. Besides the hefty are adding weight every year.
