That entire Big Bend area is really sparse on radio content. I remember visiting about 16 years ago, the dials were almost blank. You would see signs and advertisements for businesses in Midland - which to the Big Bend area is the big city! One thing that is alarming to me, at least two places I visited you could literally wade across the river to Mexico and back again - no fence, no guards - nothing. Must be a real pain for Homeland Security these days. One of those locations was on Spy Kids 2 - the water is maybe six inches deep next to the cliff, it is a little trail part way up the side for the national park. You can really see how shallow the water is. It was really tempting to wade across just to say I'd done it. That was 1997 so nobody would have cared.
