There are many hunters here more experienced than I am, but here's what I can offer. First, I should let you know that I only gun hunt, so I can't help you with bow. Second, I've always hunted private land, so it is easy for me to scout ahead of time.
1. First, just look for deer trails. Often when you are picking your way through the woods you will notice that you are on a deer trail, if you look closely. Deer look for the easy way, just like we do. If you are walking down a main trail and you see an opening in the brush at the side of the trail (even a small one), take a look at it. You'll be surprised how often it is a deer trail.
2. Again deer take the easy way if they can. Look for the low pass over a ridge (often called a saddle). The property I hunt these days has 700 ft of elevation change from ridge top to valley. You can bet the deer try to climb as little as possible. The two saddles on the property are 200 ft. lower than the tops of the ridge. Lots of action on the trails leading to the saddles.
3. It gets cold here in WNY during gun season and many guys can't take it. By noon, or earlier they are up and moving around. They stir up the deer when they start moving. Be prepared to sit all day, particularly opening weekend when the most hunters are in the field.
If I had to pick one thing, it would be sit in your best spot. Don't get up when you think you're cold (or bored). Sit some more. Let the other guy wimp out, start walking around and push the deer to you.
