This has been a fun thread, but to get serious for a minute. Our daughter is a OTR truck driver, drives coast-to-coast both north routes and southern routes. According to her, one of the things they fear are people throwing rocks and other things from overpasses, and/or bluffs overlooking the interstates. This has become a serious danger, and is happening more and more. Her advice to me, especially when driving the MH, and also when driving anywhere, is to be careful and very watchful. Her and others visually inspect each and every overpass as they approach, and try to observe vehicles or people standing or not moving on the overpasses. They try to report anything suspicious if possible. If you see anyone standing on a bridge or overpass, be especially watchful and prepared for anything.
