What's it like to spend six months walking the length of the United States, from Mexico to Canada, following a wilderness trail? Liz and Simon Willis tackled the Pacific Crest Trail in 2002 at a time many people now consider to be a 'classic era' on the PCT. They recorded conversations with hikers, trail angels and townsfolk and, eventually, assembled them into this audio time capsule of a life-changing endurance walk. Things are brought up to date in fresh interviews with people who know the trail well, including a couple who hiked the PCT exactly twenty years later.
