The main reason PA began ARs was due to massive complaints by hunters that PA deer were 125 Lbs spike and "Y" bucks. Obviously it shows that people weren't allowing bucks to grow to adults (not all hunters and deer.. just in general). So PA implimented the law to allow deer to mature a little and develop nicer racks. It's working, and I personally like it. It's nice to see deer that have a descent size to them (body and antler).
