Its a major US city, theres gonna be a homeless person or two, just dont go to the tenderloin. Its a beautiful city, perfect weather year round, tons of stuff to do. I swear some people see one homeless person and think their life is in danger.

Or just bid avoid it and save some for the rest of us. Just don't be that guy that talks crap about the city in front of the van driver or the SFO based flight attendants.
