So what does it take to keep cars out of the new Valencia Street bike lane? Well, we're not entirely sure, but a hundred determined cyclists armed with flashlights, clipboards, and printed information can't hurt. That's roughly the number of volunteers expected to take part in the upcoming "Citizen Enforcement" of Valencia street bike lanes. Haven't you always fantasized about being ready with just the right thing to say to that double-parker, and being surrounded by a group of other cyclists who support you, and having a PCO with tickets ready right there on the scene. Well live the fantasy! Volunteers will be organized into patrol groups and assigned a short hour-long evening shift. Contact Joe Speaks, Joe@Speaks.com, or 415-558-8312.
