“Everyone has a supremely low moment somewhere along the AT, usually when the urge to quit the trail becomes almost overpowering. The irony of my moment was that I wanted to get back on the trail and didn't know how. I hadn't lost just Katz, my boon companion, but my whole sense of connectedness to the trail. I had lost my momentum, my feeling of purpose. In the most literal way I needed to find my feet again.”

“I wanted to quit and to do this forever, sleep in a bed and in a tent, see what was over the next hill and never see a hill again. All of this all at once, every moment, on the trail or off.”

“When I awoke it was daylight. The inside of my tent was coated in a curious flaky rime, which I realized after a moment was all of my nighttime snores, condensed and frozen and pasted to the fabric, as if into a scrapbook of respiratory memories.”

“I was especially riveted by an amateur photograph in Herrero’s book, taken late at night by a camper with a flash at a campground out West. The photograph caught four black bears as they puzzled over a suspended food bag. The bears were clearly startled but not remotely alarmed by the flash. It was not the size or demeanor of the bears that troubled me — they looked almost comically unagressive, like four guys who had gotten a Frisbee caught up a tree — but their numbers. Up to that moment it had not occurred to me that bears might prowl in parties. What on earth would I do if four bears came into my camp? Why, I would die, of course. Literally shit myself lifeless. I would blow my sphincter out my backside like one of those unrolling paper streamers you get at children’s parties — I daresay it would even give a merry toot — and bleed to a messy death in my sleeping bag.”

“So I decided to do it [hike the Appalachian Trail]. More rashly, I announced my intention - told friends and neighbors, confidently informed my publisher, made it common knowledge among those who knew me. Then I bought some books... It required only a little light reading in adventure books and almost no imagination to envision circumstances in which I would find myself caught in a tightening circle of hunger-emboldened wolves, staggering and shredding clothes under an onslaught of pincered fire ants, or dumbly transfixed by the sight of enlivened undergrowth advancing towards me, like a torpedo through water, before being bowled backwards by a sofa-sized boar with cold beady eyes, a piercing squeal, and slaverous, chopping appetite for pink, plump, city-softened flesh.”

“Every twenty minutes on the Appalachian Trail, Katz and I walked farther than the average American walks in a week. For 93 percent of all trips outside the home, for whatever distance or whatever purpose, Americans now get in a car. On average, the total walking of an American these days - that's walking of all types: from car to office, from office to car, around the supermarket and shopping malls - adds up to 1.4 miles a week...That's ridiculous.”

“My particular dread--the vivid possibility that left me staring at tree shadows on the bedroom ceiling night after night--was having to lie in a small tent, alone in an inky wilderness, listening to a foraging bear outside and wondering what its intentions were. I was especially riveted by an amateur photograph in Herrero's book, taken late at night by a camper with a flash at a campground out West. The photograph caught four black bears as they puzzled over a suspended food bag. The bears were clearly startled but not remotely alarmed by the flash. It was not the size or demeanor of the bears that troubled me--they looked almost comically nonaggressive, like four guys who had gotten a Frisbee caught up a tree--but their numbers. Up to that moment it had not occurred to me that bears might prowl in parties. What on earth would I do if four bears came into my camp? Why, I would die, of course. Literally shit myself lifeless.
