Yep, that's Marfa. I was there with a friend for a week, then travelled to Big Bend National Park and then back to Austin with my folks. It's called big bend country because the Rio Grande takes a huge turn, making a tip of Texas that's not on the way to anywhere else in this country, but is definitely on the way to Mexico. (Thus, the unpopular plans for a huge fence along the border). Much of it's pretty far from any place with a major airport, and much of it's desert, so hard to develop. We were almost completely alone on the highway between Marfa and Presidio, although we did see some bikers (stopped in the shade).
