My point is that all the interesting stuff is not in the center. There is some interesting stuff there, but there's just as much (if not more) interesting stuff and urban/natural beauty in other less central neighborhoods like Richmond, Sunset, Pac Heights, NoPa, Castro, North Beach, Mission-Bernal, Noe Valley, Lower Haight, and a bunch more. All of those neighborhoods are safe, walkable, have plenty of things to do, and compare well on just about every dimension to any neighborhood in any big city in the world. So while the drug and homelessness problems radiating out from SoMa/Tenderloin are very serious and not to be diminished, trying to paint the whole city as a cesspool just indicates that you haven't seen much of it.
