As far as SF - everyone there seems to think they will never lose money on real estate and it will pick back up within a year or two whenever it drops.
SF was weird to me - I expected it to be a huge city, and it's this town with a cool bridge, expensive park, a bunch of overpriced houses, and a scooter app which gives you a distinct map of the "bad" neighborhoods.
