A while back I got really religous about double parkers on Townsend Street on the way to Caltrain. The double parking occurs around a blind corner out of a rotary. When you are surprised by said double parker (50% of time it's a cop, btw) you are forced into the lane which is typically occupied by a UPS truck.
I am working from home this AM (have to meet the DirecTV guy because it's easier to Tivo than download the podcasts). So I was surfing around and found the excellent San Francisco Bike Blog . It had a link to a My Bike Lane . Awesome!
I especially like this one.
