I agree with everything you said. Only problem in PA is that we have a million hunters. Maybe 700,000 these days. There is no trigger control and we have lots of guys that only hunt two days a year.
I would abide by an age restriction. Maybe 2.5 yo minimum. I would still like the option to shoot a 100 inch 8-pointer on the last day.

But there's no way we could get everyone to abide by that.
Some of us and our neighbors already hunt by these standards. What they do on the adjoining game lands is much more random.
I wouldn't begrudge someone shooting a spike or a 4-pointer. Especially if they had limited time to hunt. But we needed some way to scale back the taking of 1.5 year old bucks.
