This seems to be the area in question. Can be found on Bing Maps, but not Google(the official KGB and Pravda of the Zero Administration)There is a ranch at 27.40.34.80N, 99.39.17.33W
There is a Border crossing station at 27.42.05.70N, 99.44.32.50 W
Looking at the territory with Google Earth I see lots of fence lines, country road, small and large buildings, etc.
