In the opposite direction to that chosen Theroux, move over a quarter of a million camels annually. They were driven from Sudan and Somalia for sale on the huge market Bilesh, north of Cairo. Camels, like their black Sudanese herders in turbans (all - from the nomadic Saharan tribes) are a clear reminder of the great desert, on the edge of which is Cairo, and lying about her continent. The first part of the path to Bilesha known as "forty-day road": poor animals have to overcome hundreds of miles of desert to the Sudanese town of Dongola on the Nile. They are on the extant ancient trade route. From Dongola distilled camels to Egypt and sold on the market in Aswan near Aswan. Hundreds of animals die of starvation, surviving in Aswan herded into trucks and taken to the Bilesh, a village in the fertile area a few kilometers north of Cairo borders. It is held every week "festival of cruelty", otherwise - Bileshskaya camel fair.
