If you are driving down a country road in Kashmir in autumn, you may find yourself in a bit of a jam. Nothing as banal as trucks and cars, but great herds of fat-tailed sheep and long-haired goats will resolutely block your way. Lean men with great curving noses bark and whistle and drive the huge flock to one side, but it takes a while for the road to clear. While you are waiting, you observe the men with their turbans and kohl-rimmed eyes, the women, lean and handsome with braided hair and embroidered caps, and their children &mdash the older ones holding large, fierce-looking sheep dogs, the younger ones perched atop ponies already laden with pots and pans and tin trunks. They make a curious, exotic, anachronistic sight, these nomads.
