How I Lost My Mind–And Almost Found Myself–On the Pacific Crest Trail
Excellent.
Traversing broiling deserts, snowy mountain passes and dank rain forests on its crooked way from Mexico to Canada, the Pacific Coast Trail is an epic challenge for die-hard backpackers. White and his girlfriend, Melissa, set out, late in the season and bereft of experience, to tread all 2,650 miles of it, leaving behind lousy reporting jobs and hoping to find self-definition and a deepened relationship. (They call their trek the Lois and Clark Expedition.)
Hilarious greenhorn misadventures ensue—including the author’s ill-advised chomp, while dizzy with dehydration, into a reputedly moisture-laden prickly-pear cactus—that tested their survival skills and commitment as a couple. …
This book reminded me of both A Walk in the Woods and A Blistered Kind of Love: One Couple’s Trial by Trail.
It confirmed the certainty that I would never do a thru hike with any partner.
The biggest question I had as the sorry tale unfolded … Will Melissa come to her senses and finally dump this loser?

I can’t imagine the petty disagreements that might escalate into massive arguments while on the trail for 6 months with a spouse.
The girlfriend’s name was Allison. I kept hoping this loser would die. He seemed like a good candidate for a Darwin Award.I was cheering for Allison to dump him. He is the biggest disaster-waiting-to-happen-in-the-wilderness since Aaron Ralston (the guy who cut his arm off on a hike). Maybe the author can meet up with Jon Krakauer someday and they can bore each other to death or just have a big tree fall on them.
