sort of a dorky story, but I lost my brand new cell phone at Hiram's Haul in 2006. Got a huge ration from my spouse at how irresponsible I was. Called the hotel to check the room and lost & found. Alerted the cell company to put a theft notice on the SIM signal (or whatever they do), blah, blah, blah. Turned the car upside down searching for it, called the phone, etc. etc. ect.
Two years later at the Hiram's event, I'm pulling out my fleece from my plastic tub of sailing gear, and there it sits... DOH!
I had "outsmarted" myself putting it in there, knowing it'd be in the car so it wouldn't get lost in the hotel room.
