RE: One season, any weapon
I couldn't even imagine PA being an all weapons season from October 1-January 31. One thing is for sure I probably would never have found my love for bowhunting if it were that way and I probably wouldn't still be hunting. That would be a nightmare. You wouldn't be able to walk off the road without walking over spent shells for the first 150 yards into the woods.
I think if that happened deer in PA would have evolved into tree climbers and taken flight.
