Interestingly, what I see is a divide between North and South, more than East and West. The exceptions being Detroit and Columbus in the North and Atlanta and San Diego in the South. Perhaps this has more to do with urban planning? I just got back from Dallas (Plano, actually) and I've never experienced such relatively dense development be so actively hostile to pedestrians ... sidewalks would just stop for a quarter mile and then start again for no apparent reason.
