Bikes of Burden

"One of the main reasons for this enormous variety lies in the obsession with fresh ingredients for every meal," says photographer and Vietnam resident Hans Kemp. Kemp includes some of his best clicks in his new book, "Bikes of Burden," photos from which are available at this ABC News site.
