Since you have to hunt public, try new places often. A change of scenery keeps things fresh and you never know what you may find. Like AT said, do a deer camp and have a good time. Don't have high expectations, just enjoy the new scenery and see what you can learn. When a deer walks up and gives you that perfect shot, you'll have tenderloins to cook over the campfire.
Not everybody enjoys public land because of all the people, but it can be fun in 2 different ways. One is the challenge of trying to work around the crowd and find the deer. Finding an overlooked honey hole is always exciting. Second, it's fun to ride around camp sites or check stations and see what all has been killed on the weekend, and maybe BS with some of the local hunters.
