46 years of touring so far and only once have I had something stolen. Late at night at a rest stop on highway 5 in Oregon someone pried open the top box and stole a 35mm camera. At Crater Lake NP bear once knocked over my bike to get at some food in my top box. In the mountains of Northern California a raccoon unsnapped the vinyl cover on my Vetter fairing and ate my trail mix. At Scotty's Castle in DVNP a raven unzipped the tank paniers on my dual sport bike and ate some of my Goldfish. Yes, some ravens have figured out how zippers work.
