Well, it had to happen, and now the worrying is over. When we went out to get in our car, which we have to park on the street, the mirror on the driver's side was bent back the way it's not supposed to go. It did snap back into place, and there appears to be no scraping of the paint or contusions of the metal. However, the mirror part is just hanging on by two wires. So, I'll take it by the dealer's tomorow on our way to San Diego for the 4th of July to see if they can snap it back into place. Till then, a nice bit of clear packing tape will keep it from falling off any further, I daresay.  And we'll learn to pop our mirrors in while parked on the street.
