This is an interesting perspective on African tourism from the point of view of people who usually drive me crazy: the men who try to sell you safaris and other tourist activities the minute you hit the ground. It's making me think I should be a bit nicer. It's also making me glad that I don't often go to places like Arusha.
The author is incorrect in her definition of the Kiswahili word "mzungu," however. "Mzungu" is a word used to refer to a white person. Technically, the word means "foreigner," but you would never hear a foreigner of Asian or African descent referred to as "mzungu." Granted, most Africans probably see little distinction between "white" and "wealthy," but still.
