"This past winter, the snow stayed so long we almost forgot what the ground looked like. In Detroit, there is little money for plowing; after a big storm, the streets and sidewalks disappear for days. Soon new pathways emerge, side streets get dug out one car-width wide. Bootprints through parks veer far from the buried sidewalks. Without the city to tell him where to walk, the pilgrim who first sets out in fresh snowfall creates his own path. Others will likely follow, or forge their own paths as needed."
