SF is walkable if elevation is not a problem for you. Some slopes are so steep that it's like hiking up a trail. At least it isn't like San Jose or Newark, where sidewalks just aren't there along some roads, in residential area, or suddenly cut short in the middle of a block where you have to walk back to the previous crossing for an alternative route. And there are _so many_ dead ends without warning. So many.
