I recently spent some time living with a refugee family in the Smara refugee camp, Tindouf Province, Algeria. The family were Sahrawis, exiles from the Western Sahara Conflict, and though they had lived a mostly stationary life in Smara for perhaps forty years, they were still culturally nomads. One day, when I had been living there for a few weeks, a relative of the family turned up in a white pick-up truck with a live camel tied to the flatbed. The camel was enormous, and gave no sign of discomfort as curious children swarmed around it.
