“I come from Des Moines. Somebody had to.”

“To tell you the truth, I'm amazed we've come this far," he said, and I agreed. We had hiked 500 miles, a million and a quarter steps, since setting off from Amicalola. We had grounds to be proud. We were real hikers now. We had shit in the woods and slept with bears. We had become, we would forever be, mountain men.”

“Much as I hate to stand out in a crowd, I have this terrible occasional compulsion to make myself a source of merriment for the world, and I had come close to sealing new heights with a Russian hat. Now, clearly, that would be unnecessary.”

“I turned to my own bunk and examined it with a kind of appalled fascination. If the mattress stains were anything to go by, a previous user had not so much suffered from incontinence as rejoiced in it. He had evidently included the pillow in his celebrations.”

“It is a curious feature of our existance that we come from a planet that is very good at promoting life but even better at extinguishing it.”

“On the morning of our second day, we were strolling down the Champs-Elysées when a bird shit on his head. ‘Did you know a bird’s shit on your head?’ I asked a block or two later.Instinctively Katz put a hand to his head, looked at it in horror – he was always something of a sissy where excrement was concerned; I once saw him running through Greenwood Park in Des Moines like the figure in Edvard Munch’s ‘The Scream’ just because he had inadvertently probed some dog shit with the tip of his finger – and with only a mumbled ‘Wait here’ walked with ramrod stiffness in the direction of our hotel. When he reappeared twenty minutes later he smelled overpoweringly of Brut aftershave and his hair was plastered down like a third-rate Spanish gigolo’s, but he appeared to have regained his composure. ‘I’m ready now,’ he announced.Almost immediately another bird shit on his head. Only this time it really shit. I don’t want to get too graphic, in case you’re snacking or anything, but if you can imagine a pot of yoghurt upended onto his scalp, I think you’ll get the picture. ‘Gosh, Steve, that was one sick bird,’ I observed helpfully.Katz was literally speechless. Without a word he turned and walked stiffly back to the hotel, ignoring the turning heads of passers-by. He was gone for nearly an hour. When at last he returned, he was wearing a windcheater with the hood up. ‘Just don’t say a word,’ he warned me and strode past. He never really warmed to Paris after that.”

“Coming back to your native land after an absence of many years is a surprisingly unsettling business, a little like waking up from a long coma.”
