Great city to visit. I visited it back in 2009 and went to Alcatraz as well. Also Fishermans wharf which is a very beautiful pier like structure. Did you also visit the one street going up and down with the many corners? Don't quite remember the name..
Lombard street! Yep, went there. I was surprised to see so many parrots flying around. Fishermans wharf was pretty fun. It was neat to see all of the sea lions laying on the docks
