There are families in Colorado who didn't move an inch, but found themselves in another country.

Let's go back to 1848 — the end of the Mexican-American War. Mexico gave up a huge part of what's now the southwestern United States. When the border moved, families in the region were split apart, lost their land and more. It's the subject of a new exhibit called "Borderlands of Southern Colorado" at the El Pueblo History Museum in Pueblo.
