Hundreds of dates are written on concrete-filled steel columns erected along the U.S. border with Mexico to memorialize when the Border Patrol has repaired illicit openings in the would-be barriers. Yet no sooner are fixes made than another column is sawed, torched and chiseled for large groups of migrants to enter, usually with no agents in sight.
The breaches stretch about 30 miles (48 kilometers) on a washboard gravel road west of Lukeville, an Arizona desert town that consists of an official border crossing, restaurant and duty-free shop. The repair dates are mostly since spring, when the flat desert region dotted with saguaro cactus became the busiest corridor for illegal crossings.
