This is about people who spend many hours of their lives on buses, traveling between the rural district of Buhera and Harare, Zimbabwe's capital. Such people are usually designated ˜migrant workers; and, in Southern Africa, their movements have often been studied in demographic terms form a macro perspective. In contrast, the present book comprises detailed studies of the lives of a relatively small group of people. An obvious question, then, concerns the wider relevance of these studies. This problem of generalization is, of course, inherent in any academic enquiry as the popular saying suggests: ˜the academic is somebody who knows a lot about very little.'
