"Most of the time walking is merely practical, the unconsidered locomotive means between two sites. To make walking into an investigation, a ritual, a meditation, is a special subset of walking, physiologically like and philosophically unlike the way the mail carrier brings the mail, and the office worker reaches the train. Which is to say that the subject of walking is, in some sense, about how we invest universal acts with particular meanings. Like eating or breathing, it can be invested with wildly different cultural meanings, from the erotic to the spiritual, from the revolutionary to the artistic. Here this history begins to become part of the history of the imagination and the culture, of what kind of pleasure, freedom, and meaning are pursued at different times by different kinds of walks and walkers." -Rebecca Solnit, Wanderlust: A History of Walking
