William Wordsworth was said to have walked 180,000 miles in his lifetime. Charles Dickens captured the ecstasy of near-madness and insomnia in the essay “Night Walks” and once said, “The sum of the whole is this: Walk and be happy; Walk and be healthy.” Robert Louis Stevenson wrote of “the great fellowship of the Open Road” and the “brief but priceless meetings which only trampers know.” Friedrich Wilhelm Nietzsche said, “Only those thoughts that come by walking have any value.”
