Stickdog, you have pinpointed a puzzling and universal phenomenon -- often, when we begin backing up, folks from nearby campsites appear on the sidelines, just watching. Don't these folks have anything better to do? (Answer: evidently not.) What is so fascinating?? (Answer: this is an example of schadenfreude, a wonderful German word that means "taking pleasure in the suffering of others.")
We evolved our "stealth backup system" (no verbal commands, just a set of clear and simple hand signals) in part because we were tired of providing free amusement for the neighbors -- the frantic yelling used to attract a really big crowd. Plus, as we have gotten more competent over the years, we are less entertaining than we used to be.
Just to be clear, we have never wandered over to gawk at some poor newbie struggling to back up into a campsite. Instead, we very considerately sit in our trailer, sipping a recreational beverage, and secretly watch them through a closed window, so that they can't hear our mocking and our laughter. ;)
