The United States–Mexico border is neither the United States nor Mexico; it is rather a "third country," ten miles wide and two thousand miles long, that lies in between. This borderland, split by the Rio Grande and the border fence, is a place of transience and crossings—of people and goods as well as of ideas and beliefs. Noted photo-journalist Alex Webb has spent decades covering the border. This collection of color images shows a terrain where cultural differences between the two countries are blurred, where industrialized efficiency meets spirituality, where wealth meets poverty, and all are transformed in the process. Webb's longtime friend and colleague Tom Miller explores the concept of the border as a third country and its transformation over the past decades.
