Judd sends us word of his plight, accompanied by the above descriptive illustration of the situation:

So, on the offchance anyone on here is fuming about having a bike stolen in the Mission by Bi-Rite the other night (or knows someone that matches this description), you might be in luck. I've tried Craigslist, SFFixed, a few email lists and I'm going to be leaving a note by the pole in question, but long story short someone decided it would be a good idea to lock up their beater basket bike by u-locking it to my frame.

Yeah, you read that right. I waited a while, then unlocked my bike and hauled both bikes back to my apartment, where they now sit, both still locked to each other. Anyone have any leads? Its a blue bike, “well loved”, old Shimano 600 components, wire basket, swept bars with white track grips. It was last seen at 18th and Oakwood (in between Guerrero and Dolores) around 9:30 pm or so, locked to my track bike.

Anyone?

Judd is about to take an angle grinder to the lock and turn the bike over to Eris, but if you recognize the bike, you still have some time to save it.  Comment here and I'll put you in contact with your bike's captor.  (Side note, who the hell does this?)
