They didnt Pats. All AR's did was give about half of our yearlings a chance to grow a little older and wiser. Easier to kill a big buck in PA because of AR? Maybe a little. But a mature whitetail is a very worthy opponent no matter where you go and no matter what the rules are.
When I introduce a guy to my spot in Illinois (a true big buck heaven) I still remind him that hunting for a true mature whitetail is still one of the most challenging things a hunter can undertake. A challenge that consistently humbles even the best of hunters.
