On the southern outskirts of the city Zaranj, where the last derelict shanties meet an endless, vacant country — beige desert and beige sky, whipped together into a single coalescing haze by the accurately named Wind of 120 Days — there is a place called Ganj: a kind of way station for Afghan migrants trying to reach Iran. Every day except Friday, a little before 2 in the afternoon, hundreds of them gather. Squatting along a metal fence, Hazaras, Tajiks, Pashtuns, Uzbeks and Baluchis from all corners of the country watch the local drivers move through a fleet of dilapidated pickups — raising hoods, inspecting dipsticks. A few hope to continue on to Turkey, Greece and ultimately Western Europe. Most harbor humbler dreams: of living illegally in Iran, of becoming bricklayers, construction laborers, factory workers or farmhands.
