I lived in Marin county for a very long time. I lived in San Geronimo Valley, Fairfax, I lived in Mill Valley, I lived in San Rafael, Marshall. Went to church in Inverness for years, cooked in a restaurant in downtown San Rafael and Tiburon among other things. It was a great place to live, but you could never go back.
It’s still a very nice area, at least geographically.
There’s some natural formations not even Libs can ruin.
West Marin is that area you described. Woodacre is nice toi.
Still very little public transport between Sir Franis Drake Blvd. and places like Nicasio or Inverness.
I think perhaps most those who reside in West Marin enjoy knowing they are not easy to reach. Not quite as bad as those who live in Bolinas.
I visited Marin county last February. My uncle moved to Corte Madera in the 1960’s and raised his kids there. He is 93 and lives in San Rafael now. Had lunch at The Buckeye.
