That’s a beautiful deer but I wouldn’t say a deer like that is extremely rare in PA. A trophy and maybe a once in a lifetime size deer for some people. But plenty of deer are harvested every year that size.
Not rare at all in this part of PA. It's hard to score a buck from just one frontal pic but I would be surprised if he breaks the upper teens.
If he's 2.5, he's a solid 2 year old.
If he's 3.5, he could still blossom into a great buck.
If he's 4.5, he's behind the curve. Not that he can't still become a 150 but he has a ways to go.
