One day, three cities, five people. The trip from Douglas to Naco to Nogales is a classic look into the American Southwest.
The sun is hot, there is a sea of yellow grass, and each downtown vaguely emanates the Wild West. Along the endless stretches of highway, however, modernity breaks up the timelessness.
U.S. Border Patrol cars — fleets of white SUVs, its purpose stated boldly in green, police lights fixed to the roof — race around the charcoal concrete, searching for interlopers.
