RE: PA antler restriction
AR's are the best thing to happen to this state. Your best outlook is to not listen to the grumpy old rantings of bitter guys like your dad (and mine).
You will do much better to keep an open mind and postive attitude both in life and hunting.
I have no sympathy for those who quit doing something they supposedly loved, just because of a tighter restriction.
Good luck this season, stay positive, and have fun in the woods. THAT's the main goal of hunting.
