South of Hugo, Colorado on Highway 287, the land is wiped clean, the prairie grasses and flowers of spring cut to the root by cattle, their shining white teeth. Dung, dark stains on the land running the fencelines, remnants of progress, the way we produce meat in this country. It cannot have rained in many days. These hard-pan flats, the leading edge of the Great Plains east off the Rockies, turn a dust devil against the horizon to the south.
