I dunno, man. The first time I visited SF was in 2001. I was stunned back then by the homelessness problem. I vividly remember walking down the sidewalk near the Transamerica building during the morning commute and seeing folks in business attire casually stepping OVER a person sprawled out in the middle of the sidewalk. Nobody cared, even then, because it was normal. On subsequent visits, I’ve seen plenty more homelessness, had a bike seat stolen, etc. If you had a good experience a decade ago, awesome, but you also sort of got lucky if you didn’t see any of the other problems. Maybe it’s worse now, but from the standpoint of someone who grew up near Boston (which also has plenty of homeless folks and addicts), it never seemed “tourist excellent” to me. It’s a real American city with all the standard problems.
