We are in San Francisco! For 45 minutes! But long enough to get a sandwich at Boudin's. When we got off the plane we were impressed with the state of the art self-service kiosks for customs. Suddenly they all went out. After about 15 minutes a man brought a stack of CDs and gave one to each officer. "So if they are not on the list, they're OK?" I'm sure it works really well when it works.
