Honestly, the idea that SFBA is post-apo?

I finally acquired it by visiting in 2015. Landed at SFO, went through pretty mediocre airport, then visited SF... and went "hey, this looks more like middle east war torn country than what I expected" - and my expectations were already dashed by things such as crowdsourced maps of tenderloin based on quantity of human feces on sidewalk.

Thing is, my mental model assumes that other places in USA are probably worse, if not in the same ways.

But the immigration system is biggest stopper, even for visiting, indeed.
