OTAY MESA, CALIFORNIA—In late May, I drove a rental car down the California coast to Otay Mesa, the third busiest border crossing in the United States. The land port sits 20 miles south of San Diego and inland from the Pacific Ocean, and processes up to 55,000 vehicles, mostly semi-trucks, filled with agricultural and commercial products daily. In 2019, then-President Trump visited Otay Mesa to hold a press event at the construction site of the U.S.-Mexico border wall, calling a new design fortified by 18 and 30-feet walls running parallel to each other “virtually impenetrable.”

Driving southbound on U.S. highway 805, a series of white and green signs—“GUNS ILLEGAL IN MEXICO” and “LAST USA EXIT”—indicated I was arriving at the border. I veered off the 805 onto a smaller highway, and my eyes locked on a monolithic block rising from the hillside.
