I'm pretty obsessive about my bike. If I have my back turned on it for a minute, it gets locked. When I swim, I take it through my club and back to the pool area. Then, even though parked only 10 feet away from where I'm swimming I still feel compelled to put a lock around it.

I was in Starbucks and even though the bike was just outside the window, my back was turned on it while I was ordering so I still locked it.

I never park my bike unattended outside for any length of time. At work, it lives in my classroom. At home it goes in a locked garage.

Do you think I'm ok just carrying a little cable and paddlock and leaving my heavy U lock at home? What experience do people have leaving bikes unattended and locked for very short periods of time and having them stolen?
