Let’s get a little nerdy, but in a fun way. The border is nearly as long as the distance from New York City to Denver. That’s a lot of ground to cover.
It touches four U.S. states: California, Arizona, New Mexico, and Texas. On the other side? Six Mexican states: Baja California, Sonora, Chihuahua, Coahuila, Nuevo León, and Tamaulipas. So they’re frenemies by geography.
Here’s a mind-bender: that border is twice as long as the Great Wall of China. But instead of ancient stones, we have fencing, cameras, and the occasional tumbleweed.
