I remember visiting Columbus, NM about four years ago. Seemed like the end of the world, and VERY easy to cross back and forth across the border.
It does seem like the end of the world. It's really is surreal in many ways. What became pretty evident today is that there are a lot of place they will simply not get across...at least not in massive numbers. I can see a fence and the level of enforcement focus I observed having a big impact.

A zillion years ago I went on a field trip to Columbus (for a college class on Zapata). We strolled across the border into the little town there (I forget the name) and had a beer (because we were under age in the US). I don't recall any kind of anything to stop us, altho my memory may be fuzzy. I also remember it seemed like the end of the world, even to a New Mexico girl!
