I cannot stand to carry my wallet in my back pocket. As a result I have lost mine twice. The first time I was getting gas near home and left it on the truck bed cover. I went back to the gas station and walked up and down the road till I found it, aside from being a little flatter it was fine. Second time was in Rome, GA and I looked for at least an hour and never found it. I was at a hotel and I assume I left it on the truck bed cover when I was putting everything else in the truck when we were about to go out. A week or two later I got an envelope in the mail. Someone on their bike had found it and sent it back to me. I sent them a thank you letter and a waffle house or cracker barrel gift card.
Almost lost my cell phone the same way, when we got home I found out it had gotten stuck in the luggage rack on my wife's car that I was driving. We stopped about an hour from home and apparently while I was waiting on everybody else to get to the car, I laid my phone on the top of the car.
Fortunately I have not had a repeat performance yet. It's a pain.
