Fourteen years in the making, this is a chronicle of the nearly two-thousand-mile international line between the United States and Mexico. It is an historical account largely through the eyes and experiences of government agents, politicians, soldiers, revolutionaries, outlaws, Indians, engineers, immigrants, developers, illegal aliens, business people, and wayfarers looking for a job. It is essentially the untold story of lines drawn in water, sand, and blood, of an intrepid, durable people, of a civilization whose ebb and flow of history is as significant as any in the world.Award-winning historian Leon Metz takes the reader from America’s early westward expansion to today’s awesome border problems of water rights, pollution, immigration, illegal aliens, and the massive effort of two nations attempting to pull together for a common cause.
