- Chicago, IL: The L reaches a lot more neighborhoods, is a single integrated transit system. - Columbus, OH: Great bike lanes and dedicated paths, bus system that covers the entire city. - New York, NY: By far the most walkable city in the US. - Philadelphia, PA: Decent subway system, good connection to NJ and NY via NJ Transit. Very walkable core and neighborhoods. - Washington, DC: Far superior version of BART with a lot more coverage.
Unless I've just happened across a half dozen of the best cities in the US, SF isn't all that remarkable.
There are bound to be some pretty cool places in AZ, NM, TX, and the southeast. I've been casually researching this topic for a while, and I've found it to be incredibly difficult to find a useful, non-biased index of walkable and interesting neighborhoods from all corners of the US.
Good luck!
Have you tried to apply for a job? Don't underestimate yourself. I had the same thoughts about myself, then I tried an interview just for fun. Now I'm working for a FAANG company, moved to Canada, and having the best year of my life.
