I just got back from the same screening at the Victoria..I locked up my bike to a pole that was by the entrance of an alley kitty-corner from the theatre. I checked to make sure the pole was secure and that it couldn't get pulled out and also that the top of the pole had a secure sign on it 'cause I''ve heard of thieves sometimes sliding locked bikes straight up and off a pole. I didn't want to **** with that whole 'lock my bike up with a hundred other bikes and then have to wait after the show to retrieve it' deal....just seemed like a pain in the ass. Thank christ my bike didn't get stripped...I've got a Brooks and Phil's...By the way, where did you lock your bike up? Was it in the alley across the street or DIRECTLY across the street? That sucks someone did that to you..I wonder if maybe they know you/your bike and have a vendetta against you? Or just the usual lack-of-respect/greed thing.
Hopefully you'll find out who did it and break their face with your u-lock.
