Re: How not to hook up a trailer.
to continue the CSI:
could be the top ball is too small and that's why it's covered over-and the guy didn't know any better, or he had no choice.
Or he had to use the too-small ball b/c the other one is too big (not likely)
Or his receiver is rusted in and he couldn't get it out. Happened to me once and it was an ordeal to get it loose.
Or he lost the key to the lock on the receiver
Or he's just moving the boat in the driveway and resting it on the ball nut was all he needed. the reason I doubt this theory, though, is that he also hooked up the lights and brakes. But I remember people moving padlocked trailers at a marina that way to get them to higher ground before a storm came.
but who would take the picture, and why? A passer-by?
