I'm sorry for your loss. You're not the only one. I've had 4 stolen from me in 20 years here in LA. All of them vintage 10 speeds, and all but the last one not worth much. The oddest theft happened when I leaned the bike against a building in broad daylight and went up a flight of steps to knock on a friend's door to see if he was home and wanted to join me for a ride. When I got back down (what, 90 seconds?) the bike was gone! A group of drunks were sitting across the street and I asked them if they saw who took it. They I.D.'d the guy as a local crack fiend. I confronted him later and he fessed up, and then got me a temporary bike from a friend.
The last theft was in summer of '07 when my prized vintage was stolen from a storage unit on a "safe" property. The property owner felt so bad he offered to buy me new one. That began my entry into the world of modern road bikes.
