The Border Patrol agent watched our Prius approach, then signaled for us to stop. Behind him stood several others in green uniforms, hands resting on holsters, eyes hidden behind sunglasses. German shepherds panted in the heat. “Are you all U.S. citizens?” the agent asked, leaning against the driver’s-side window and glancing around our car. “Yes,” said one of my companions, an artist from Iowa. “Yes,” echoed the other, a poet from Connecticut. Then it was my turn. “Yes,” I said. The agent’s gaze lingered on me for a moment. Then he stood up and waved us through the border.
Except this was not a border: This was the middle of Interstate 10 between El Paso and Marfa, Tex. No matter. At the Sierra Blanca checkpoint, agents can make arrests for drugs or weapons, share information with federal agencies and turn undocumented immigrants over to Immigration and Customs Enforcement. There are many such checkpoints scattered throughout the continental United States — borders within borders.
