“San Francisco is nowhere near as nice, friendly, decent, vibrant, clean, orderly, or fun as it was 20 years ago. “
You should have seen it 50 years ago.
I went to SF 24 years ago on my way to Maui. Even then the homeless population was worse than any other US city. There were still parts of the city that were worth visiting. You could also see why it was so great in the 1950s & 1960s. Now, I would not go to any California city.
Five years ago we went to Oahu and the Big Island. Took the Hawaii Air flight from Boston direct to Honolulu. 11 hours going there. 9 hours back.
