Public land is just that, public land. If you go there you must deal with the publc. What some consider common courtesy is not all that common nowadays and seems to get less common as the years go on. I don't know of any cure for humanity except to get away from it. Either hike farther in or acquire some private hunting land.
Down here in Texas there is not much to chose from for public hunting land and what there is is way too crowded for my taste. Most people I know either hunt some friend or family members land or pay for a lease, which is what I do. Even then you have others hunting with you and must deal with their way of doing things. But ya know, it would be a very boring world if we were all the same.
Hell, we'd all hunt with the same gun!
