Equal distance from DAL, AUS, and IAH is about a 2 hr drive to all three airports. Kosse, TX is between 1:55 and 2:10 to all 3 airports. I'm not sure people are aware of how uninhabited the western U.S. states can be. The overall population density, including the significant impact of SoCal, is about 1/3 Europe's population density. Wyoming has 6% of Europe's average population density. Overall the U.S. west has the population density of Norway. Compared to the larger European countries the density of the western U.S. is 5-10%. And individual states can be misleading - Nevada is ranked as average. But 73% live in Las Vegas. The northern part of the state is barren.
