Interesting. I work in San Francisco near the Ferry Building and frequently jaunt down to Pier 39 on my lunch break for exercise. Tourist alley, especially now that they have a new cruise terminal between the Ferry Building and Pier 39. Just today I nearly fell into a couple who stopped to take a picture of Coit Tower, speaking in an English accent. I moved on and got out of their way. 'Tis different when the shoe is on another foot, I suppose.
