Bucks in general that I see. Before AR I would hunt season after season and the best buck I would see might be a 2.5. In the last season I saw many that I would consider to be near mature. I'm not that good at inventorying and aging every deer in the woods. What you call mature and what I call mature is the question. A 3.5 year old buck is a sight to see in the PA woods and I personally would like to see a few more. I actually wouldn't shoot a 2.5 year old deer anyway, so if AR was supposed to supply only 2.5 bucks, I don't think it goes nearly far enough.
I have tagged enough 1.5 and 2.5 bucks that I let them walk now, that's just me though. I'm not intent on filling a tag, I want my tag intact when I get a shot op. at one of the ones I've been seeing lately.
