Tim Cahill's additions to the World Hum Top 30

Back in May, World Hum's Top 30 Travel Books of all time included Tim Cahill's Road Fever, which occupied the #21 slot in the countdown. Since I know Cahill from the Key West Literary Seminar, and also from my online interview of him in 2004, I emailed him to see what he thought might be missing from the Top 30.
This is what Tim told me:
Very subjective about the books, but Edward Abbey's Desert Solitaire was my personal inspiration. Also:
The Worst Journey in the World, by Apsley Cherry-Garrard
News From Tartary, by Peter Fleming
Annapurna, by Maurice Herzog
And several dozen more that we'd have to force ourselves to drink many beers in order to recall (while remaining completely sheveled, of course.)
