Did you ever find anything of interest/worth?
DH found $100 under the windshield wiper of our rental car at the Alhambra a few years ago.
No explanations.......it was bizarre.
So he went back in, stuck it in a machine,played it and promptly (like magic) it turned into $0.
Another time i found dentures on a plate on our patio at Renaissance.
Housekeeping brought them to lost and found.
