The ferry to Larkspur. (No, that's not Cyn.)
Also from the ferry trip. This is San Quentin Prison. For most of the trip, I could not get Johnny Cash out of my head. I saw Folsom Prison when I was wandering around the map. And we went through (or near) Jackson (We've been talkin' 'bout Jackson, ever since the fire went out.). For some reason, I woke up one day with "Hey Porter" going through my head, and it was stuck for quite some time. When we were at Alcatraz, the phrase "hey warden!" went through my head, and translated into "hey porter" and the song came back. At the moment, I've got "God's Gonna Cut You Down" in my head.
Windmills on the hills just to the west of the city. Thousands of them. I could be wrong, though. Maybe tens of thousands. I was impressed. Here in Wisconsin, a big wind farm is a dozen windmills.
This was on the Skytrain at SFO.
