Few people know how to take a walk. The qualifications are endurance, plain clothes, old shoes, an eye for nature, good humor, vast curiosity, good speech, good silence and nothing too much. – Ralph Waldo Emerson

How can you explain that you need to know that the trees are still there, and the hills and the sky? Anyone knows they are. How can you say it is time your pulse responded to another rhythm, the rhythm of the day and the season instead of the hour and the minute? No, you cannot explain. So you walk. – Author unknown, from New York Times editorial, “The Walk,” 25 October 1967
