Day 3: I was not prepared to be blown away by the Palace of Fine Arts in the Presidio. But I had been warned to walk through Fisherman's Wharf one time then take my money and run. Good advice.
The highlight of the day was the five hours we spent on Alcatraz Island touring the drafty cell block and feeling sufficiently creeped out...which was perfect, actually, considering it's the only maximum security prison (of it's day) we've ever walked through. Night Tour highly recommended. Ultra creepy.
