|We left Kano's dusty streets and headed southeast, across miles of featureless savanna. Although the scenery remained uniform, the people did not. Nigeria has no fewer than 250 peoples speaking nearly as many languages in a total of 400 dialects - one of the world's most linguistically complex regions. The prominent tribes are the Yoruba in the southwest, the Igbo in the southeast, and the Hausa in the north. We use English everywhere and that's enough to get by thanks to the legacy of British colonization. To the bad side, Kathy our tour leader is sick with malaria again. Having malaria once doesn't lend a person anymore protection against catching it again.
