Why I Walk An Article by Chris Arnade walkingtheworld.substack.com On my first day I literally walk across the city, to the extent it can be done…The next day I do another cross town walk, but in a different direction, filling in the blanks from the prior day’s walk. Then, over the next week(s), I walk between 10 to 20 miles per day, picking and choosing from what I have seen before, highlighting what I like, what I want to know more about, refining the path, till by the end of my trip, I have a daily route that is roughly the same. While that is certainly not the most efficient way to see a city, it is the most pleasant, insightful, and human. I don’t think you can know a place unless you walk it, because it isn’t about distance, but about content. walkinghumanitycities
