For our last full day in San Francisco, we decided to go on a boat cruise. We had a 2 hour "Bridge 2 Bridge" boat cruise with the Red & White Fleet where we sailed from Pier 43 1/2, under the Golden Gate Bridge, around Alcatraz, past Treasure Island, under the Bay Bridge, and then back to the pier. While in line for the cruise, we saw Obama flying over the bay in Marine One!
