(CNN)Take a walk through the oasis of green grass and palm trees in the central plaza of the tiny Sonoran Desert town of Ajo in southwest Arizona. You're likely to run into a Native American from the Tohono O'odham tribe, a Hispanic from the United States or nearby Mexico, or a white person, whom the whole town refers to as Anglo.
