Miniature Horse, Kentucky, 2003Photograph by Melissa FarlowA miniature horse stands in a field near Lexington, Kentucky, a bit of a curiosity in a region known more for its regal, fleet-footed thoroughbreds. There are some 500 thoroughbred horse farms in and around Lexington, where pastures, fed by the rich leavings of a long-vanished sea, are said to be among the world's best.
