One more FYI: people from San Francisco rarely, if ever, refer to it as anything else but San Francisco, at least when spoken. E.g. they would not say "SF" out loud, and will never, ever, say "San Fran."

You occasionally hear "SF" spoken aloud, especially when the city's name is being used as an adjective, but by far more common is "The City".
