Getting up at 8am again (this jet lag goes away fairly quickly), I met up with Thomas, Jon and Alex at 10am and we went to the Zoo where there was a distinct lack of animals in most places. Jon went off on his own as he had a flight to catch mid-afternoon. We had lunch (Chicken burger) some time after 1pm at Bill's Place which has a nice outside patio area at the back.
Around 3pm we walked across the Golden Gate Bridge to Marin County and back. It took almost two hours to get from there to Pier 33 where we met up with Jeff, Koen and eventually Colin, Adrian and Crystal to get the ferry across to Alcatraz for the night tour.
They give you headphones for an audio tour which goes very slowly and makes it easy to lose track of where you are on it. Most of us stayed until the last ferry back. Thomas, Colin and I then met up with Jeff, Koen, and some friends of theirs at a place called Mars Bar around 10:30pm until closing time.
