Seen some places on Saturday, and hope to have photos posted when I get back.
Took a bus tour of the city, and found some pretty interesting tidbits on the Civil War history of the San Francisco area. One of the top CW highlights was Fort Point, which is located right under the Golden Gate Bridge. The tour guide mentioned that the fort was modeled after Fort Sumter, but wasn't completed at the end of the war. There seems to be a group that does living history there, but I don't know if they had a program going on.
The tour guide was a pretty good hand at CW era history, and gave me a quick run-down of Alcatraz Island's military history.
