That's only part of the difference. And even back then, some were grumbling about not seeing enough deer, because other places had more deer at the time. Guess who they blamed then?
That is simply your biased opinion. Where I grew up we had very few deer in the early 50s and just seeing tracks was news worthy. No one hunted for deer because it was a waste of time and no one complained or blamed the PGC because no one ,not even the PGC experts expected that the southern tier counties would provide the best deer hunting in the state. The herd increased and we had good hunting until the pGC declared that the goal for 5C was 6 DPSM. The habitat in our area can support over 90 DPSM but the fools at the PGC claim it can only support 6 DPSM. IMHO that is total incompetence on the part of the PGC.
