I visited SF on other occasions in 2015 and 2022. The contrast between 2011 and these dates was staggering. In 2011, I did not have to step around human feces in the street. There was and is always a significant presence of homeless people -- who don't bother me -- but at least back then, I felt pretty confident walking at night through any part of the city, even the Tenderloin. In 2015? It was pretty bleak. Crime was up, and folks were much more aggressive. In 2022, I had my head on a swivel. I'm used to significantly more, uhh, vigorous urban areas, and SF started pinging my situational awareness in 2022 like it didn't eleven years earlier.
Don't get me wrong: SF is a kitten compared to Chicago, Detroit, or Baltimore. But, it's sad that it has descended so far. It is still a charming city that I'd love to visit again, but some of that charm has been lost.
