Not sure why this is a classic. Guess if you're Graham Greene, anything you write is considered worth reading. Greene had no idea what he was doing and no business doing it. And, worst of all, he didn't enjoy himself at all. The book reads as a long complaint — the heat, the food, the native carriers' laziness, the officials, the bugs, the rats, the boredom. He hikes as far as he can everyday, pushing everyone else to the point of misery, just so he can get the journey over with. The book was irritating and gave me the impression that the author would be too.
