I agree with what's already been written but I would add that deer do still come through the good looking spots on public land even though there's a guy hanging from a tree in that area almost every day. They just move super, super slow and will manage to spot just about every hunter. They skirt around the guy and keep going where they're headed. My advice is to be as well hidden as possible. The more branches and leaves around you, the better. I don't think going a little higher helps you very much in places where deer are hunted hard every day. Also, be very selective about when and how you move.
