I don't have a lot of love for Marin County.  For one, it's the place that mountain biking was invented, yet all the seminal trails are now illegal to ride on. Second, everyone there drives BMWs and nothing irks me more than other people's success.  Plus, it's San Francisco's Canada.  But when it comes to bike lanes, they seem to have the right idea.  Drivers always seem to park their cars in SF's bike lanes (I blame tourists, cuz they're dumb).  It took SF years to do a damn thing about Fell.  And it's Monday morning and I need something to bitch about.

Would a simple “no parking” stencil along all the bike lanes help?  I certainly don't know for sure, but I've only had to bike around a car while shaking my fist once up there.
