The New York Times's Travel Section interviewed Robert Macfarlane about his latest book in his trilogy of books on observing place, history and imagination. "The Old Ways: A Journey on Foot" is about walking the old trails that exist all over the world. They have connected people for centuries. In a way these trails were the predecessor to our electronic communications, like the phone and then the Internet today. They formed a connecting web to meet and explore other people and places.
His fascination is that the old paths promise a way of walking deeply into, rather than just shallowly across, the landscape. Although I have not yet read the book, its on my priority list.
