I was thinking about this question because of the snow/ice storm that has hit many of the southern US states this past weekend. I had to walk to a neigbhor's house when I realized that I have never once in my life seen a sidewalk that's been cleared of snow and ice. The roads where I live are both salted and plowed but the sidewalks have nothing, or worse, the snow from the road has been piled up onto the sidewalk. Everyone just kinda walks in tge street and jumps out of the way when a car comes. Is this a common thing everywhere? Or, does my city just have bad infrastructure because it doesn't care about walking and/or is too southern to develop good winter weather infrastructure?
