On the road, again. Crossed the Bay Bridge, mid afternoon. Visited Fisherman's Wharf, Ghirardeli Square and Chinatown. Saw Alcatraz Island and Coit Tower. Stayed at the Holiday Inn-Express on Van Ness, in the heart of the city. (26th, top floor). Excellent hotel and on site restaurant. Tomorrow we plan to ride a cable car, drive down Lombard Street ("the crookest street in the world," paved with red bricks) with its hairpin turns, one way, downhill. Then, we will cross the Golden Gate Bridge and continue north.
