He would take the ferry from SF to Marin (no bridges then) with his model 12 broken down in a canvas case, then take the train out to a train stop called Buchli Station, the old building is still standing. From there it was about a mile walk to the ark. I live about 3 miles from where the ark used to be and I still hunt some of the same areas he did. When I was a kid we used to cruise the sloughs and he'd show me his old hunting spots. He always rowed his boat, outboards were notoriously unreliable back then. I hunted with him until he was 85, he passed at 91, in 1997, BTW, both he and my grandmother were SF earthquake survivors.
