Bored and fed up with life, staring down a fiftieth birthday, Mike Tyler was looking for a change. Life had become routinized and unexciting. Maybe it was a mid-life crisis, or maybe just a yearning for one last big adventure. Mike decides to try hiking from Mexico to Canada on the Pacific Crest Trail, just to see what happens.

Mike convinces his wife, Margo, to join him. Together they embark on a five-month hike full of anticipation. They hike through some of the most stunning and remote places in the country on a trail full of unique, offbeat characters. But the trail had even more to offer than either of them had anticipated.
