Shamalzai District, Zabul Province, Afghanistan—The village of Sher Khan Khel sits at 7,221 feet, a few miles from where Zabul Province borders Pakistan. Stone and mudbrick houses dot the barren slopes (there is little that will grow at this altitude). Women wear dresses trimmed with coins and ink tribal tattoos on their faces, while the men are clad in traditional shalwar kameez and turbans. There is no electricity, no cell phone reception, no TV service. When I visited this spring, I asked a few men how far a nearby village was from another. "Two to three hours walking," was the answer.
