I agree that public land can be a hassle. Last year I was mainly hunting public land and hadn't done my homework. I ended up getting frustrated with all of the other hunters and ended my season a bit early. For turkey season though, I did my homework and found a few spots ranging from 3/4-1.5 miles away from the parking area. I got my bird and never saw another hunter where I was hunting. It's all about finding a spot that's far enough that other hunters wont go, and that's loaded with game.
