I was in the parking lot of a local WalMart when I saw a 35mm film container laying on the ground. Then I noticed it had a Geocache sticker on it. A nearby lamp post had been vandalized, so I deduced that the cache had fallen out and never even noticed by the vandals. I put it back where I thought it belonged and, on line, was able to identify the cache and notified the owner of what happened.
Claimed the find, though.
