The Pacific Crest Trail offers many kinds of experiences for trail users.
Hiking, yes... but beyond that, what you take from the trail is as different as your mind is from that of the next hiker.
Martin Bunzl's mind focuses on philosophy, a subject he taught until his retirement from Rutgers University, but math and science take the trip too.
He shares deep thoughts on the relationship of humans to nature in Thinking while Walking: Reflections on the Pacific Crest Trail.
The author visits to talk about the trail sections highlighted in the book, and the thinking they spurred for him.
