As they said go and be a "deer watcher" in areas where you might be able to public hunt. Get a climbing stand and learn to use it and a safety harness and climbing rope. Watch where they move and learn to pick better trees for your stand. You'll start to learn how to notice deer trails after you are out observing more. Learn to walk farther on public land as most people won't and you'll see more deer during the season.
Get yourself a compound bow and learn to shoot it. Being a newb in rifle season, without help, would be overwhelming and maybe dangerous. I would imagine deer get chased off state lands in PA as I know they do in MD. We have a few mountain state lands near me and it looks like orange dots on the hill rom the road. No way, I would want to be out there during rifle as it is too many shooters and that many hunters and the deer aren't there.
Don't worry about shooting a buck and take what ever game the state allows ar first. You can define your ethics of game choice after you know what you are doing and have killed some and learned some. Don't let people define your choice for you.
Hunter safety class are just canceled right now and will be back when the craziness ends.
