Bike Registration that Works

Atim, the Saint of Oakland, bought it from guy fencing it on San Pablo for $40, hunted me down online, found me on Bike Index, returned the bike, and refused a reward until I forced him to accept one. This all happened about one week after the theft. Atim, if everyone were like you, we'd be living on a higher plane...
