Most public campgrounds don't have any restriction on overhanging the pad. Many private ones do, and a few public ones. I've been to Pickens several times and I don't recall any rules on it one way or the other. Seems most of the sites I've been in lately have trees or walls or something solid behind the site so overhanging it is impossible.
