San Francisco bay.
We kicked off the day with a cable car ride all the way up Powell to Fisherman's Wharf. We then legged it round to Pier 33 to the ferry boats.
The trip over was short and sweet - great views of the city and the Golden Gate Bridge.
Once we got there, Alcatraz Island was way more interesting than I thought it'd be. Lots of history and really well presented. Ok, way too many tourists but we coped. Just.
Angel Island was Ok too but we could have perhaps done without the hour long tram tour.
