Last year someone at work decided to steal the tail light off my bike. I parked the bike in the lunch room and thought that it would be safe there. Little did I know that someone took the time to fully unscrew the tail light off the bike (including the clip that holds it in place) and that there is a thief among my co-workers. And while I admit it's my fault for not knowing better that time, it is quite sad and pathetic to steal a tail light which costs like 15 BUCKS

Now, I take off both of the lights and lock up both wheels with a U and Cable lock while the bike is parked in the lunch room.
