You are right about the15th, but it's antler less only! I'm not going to hunt my stands until I can shoot a buck. In the area I'm in the buck needs to have 3 points on one side before its legal. I use a compound bow, but I do have a crossbow. Don't use it much, unless I'm on the ground sitting near a trail without much cover.
I don't anything in front of me, I'm pretty sure it needs to be an inch. I agree with you on the herd size. I'm not from PA, but I've lived here since I've retire from the air force and you can tell the herd size is smaller, but some areas have such a large population because of hunting restriction. It almost seems as they are basing tag limits on those areas. I live in area 5C and there used to be a very large population of deer, the almost unlimited antlerless tags seems they are based on counties that have very restrictive hunting areas. Its a bit confusing to me.
