Well, I asked the lock what it was doing there but it blew me off.
The lock was located downtown in the city during the middle of the work day. So:
- If it were a commuter wouldn't the bike be there?
- If the commuter were running errands wouldn't he/she take the lock with them to lockup at the errand destination?
Until we get a straight answer from the lock, I'll assume that a rider either:
A) Locked up around a fork or something and the bike was taken.
B) Lost the key and cut his bike loose and salvaged the remains.
