ARRRRGGHH!!!
Once many years ago I was yanking parts in a junkyard, sitting crosslegged on the ground, and dropped my 7/16 socket from my Penncraft set, the first good mechanic's tools I ever owned. It fell straight down into the triangle formed by my legs. I spent half an hour searching, could not find it. Leaves and grass, but really! I had it located in ONE SQUARE FOOT and never found it.
This was after JCPenney got out of the tool business, so I replaced it with a Craftsman. Bugged me no end until years later, found a Penncraft to replace it. My Penncraft collection is growing, but fear not, I'm a USER/collector.
Hey, NiceToy- speaking of rental cars, I found a camera in one. A pretty nice Nikon 35mm point-and-shoot. (this was waaaaaay before digital). My left shoulder and right shoulder angels shouted at each other until I decided to split the baby. When I returned the car, I had the camera in my pocket. If the clerk said anything about a missing camera, I would turn it over. If not, I would not mention it, since of course any low-paid clerk would surely grab it and pocket it. (such is my faith in humanity). He said nothing. My next step was to develop the film. It had only a few pictures, and they were of an incredibly generic suburban house with absolutely no clues as to location.
Oh, well.
I kept the camera, used it a bit, and finally sold it on eBay for, I think, $2, after the digital revolution had become obvious even to me. Well, it was a Nikon. Maybe it was still worth $2.
