I don't think most housing advocates want to pave over parks and things like that, but want to add some options where there is already a town.
Also, as kind of an aside, Marin NIMBY's pretty much killed mountain biking in its birthplace, which I also find sad.
Cross the bridge, take a left, and drive out to the national seashore. Have lunch in Pt. Reyes. Drive back out to the 101 through the Nicasio horse country.
Thank you, thank you, Marin County NIMBYs. Thank you.
