Word.
I've had some fun rides w/SDBC but that kind of ******ry and dangerous behavior is all too common. I mentioned riding with them to a friend who is a very experienced local cyclist and he said "SDBC stands for Super Dangerous Bicycle Club." Every time I've been out with them there's been a report of a crash or a near-crash, in part because of knuckle-headery like that. Granted they do good things for cycling in San Diego, but still-- rider beware!
