Query: A bitter book

Wow!Here is a guy that gets an opportunity of a lifetime. Touring Africa for seven months.Instead of hearing about some of the wonders of Africa, this author would rather 'bitch' about his traveling companions.He seemed much more concerned about how much food he could get, throwing bottles because somebody pitched a tent too close to his or making fun of the tour guides.What a guy! What a waste of ink, time and money!Just sorry I bought the hardback edition.
