Imagine you decided to walk from San Diego, California, to Brownsville, Texas. That’s the entire border route, and your Fitbit would probably give up on you halfway through. It’s roughly the same distance as driving from Los Angeles to Seattle, but with more cacti and fewer coffee shops. You’d also be walking through four U.S. states: California, Arizona, New Mexico, and Texas.
Let’s put it in terms we can all laugh at. If you drove a 1969 VW Beetle at a steady 55 mph, it would take you about 35 hours of non-stop driving. That’s longer than a season of your favorite Netflix show. And yes, you’d definitely need a bathroom break—maybe about 97 times.
The Not-So-Glamorous Reality: A River and a Fence
About two-thirds of the border follows the Rio Grande River. The problem? That river loves to wander like a toddler in a toy store. It changes course, meanders, and sometimes just decides to be a puddle. So the actual “line” on a map is more of a suggestion than a ruler-straight boundary.
The other third is marked by a series of fences, walls, and barriers. Think of it as a 700-mile-long “please don’t climb” sign, but with more steel and fewer cartoon characters. Some sections are just barbed wire, while others are 30-foot metal bollards that look like the world’s most aggressive picket fence. It’s the kind of fence that would make a suburban dad jealous—if it weren’t so expensive to maintain.
