In Marin County, there are no double yellow boundary lines on US101, but the CHP patrols the fawk out of the lanes throughout the county, ready to nail scofflaws from overpasses by portable photo-radar. :upset: At $271 minimum per violation, it's the biggest fawking cash-cow in years, this side of the DUI patrols (which I wholly endorse BTW).

So the liklihood of diamond lanes dissapearing here anytime soon is virtually nonexistant.
