None of the back stories on any of my pins have been too interested when I asked the owners about them (mostly them just getting them from people who fix them up) but I'm sure some folks out there have got or heard some pretty interesting stories about where their pins came from.
The closest I got is buying a pinbot the owner who bought it from some place in mountain holler arkansas, which is where the person who got another pin i was looking at said they had gotten theirs. small world.
