I think we did everything you are meant to do at Fisherman's Wharf! We bought chocolate from the Ghiardelli shop, and fridge magnets and a t-shirt from one of the thousands of tourist shops. We had sourdough from Boudin and admired the sea lions. Actually the sea lions were awesome and we watched them for ages. Brad looked briefly at the ships and the submarine. We went to the Maritime Museum - I wasn't super interested but Brad said "it's the building, not the contents" and he was right. A way cool 1930s building with fabulous original murals and mosaics inside.
There weren't a lot of people around so it was really pleasant to wander and look at things. I think it can get a bit crowded in summer but we found it really laid back.
And in the afternoon we were off to Alcatraz! That is a high volume tourist experience compared to most of the things we were doing, but I guess you need a bit of clockwork efficiency getting people on and off an island. Looking back I hardly took any photos at all, and none inside. I did find it quite confronting and unpleasant - which I shouldn't really be surprised at. But it did surprise me, how much of the grimness remained. I think they should raze the whole place and make it into a park, but I know that's not very historically sensitive. I do tend towards the astroturfing of past unpleasantness wherever possible.
The best bit about Alcatraz are the views back towards the city and over to the golden gate bridge. This sky gives a true indication of the weather. Brilliant sunshine, rainy squalls, angry looking sea and clouds.
