Very cool ending. I lost my class ring 3 months after I got it. On a summer trip with my parents, the popup got a flat along the highway so I got out to help. There were other things on the popup's roof, like a drink, lug nuts, so I took my ring off so it wouldn't get damaged and put it with the other stuff.
A mile down the road... "Mom, did you grab my ring when you grabbed your drink?"
Went back and walked along the road for a mile. I figure it got under someone's tire and was flung far, far away. I'm hoping to get one of those calls 30 years from now because someone found it and tracked me down (my name was inscribed inside). I'm not holding my breath.
