I'm very concerned about travel in Texas now. Texas has a great freeway and highway system (we ought to. It's CONSTANTLY under construction), and driving, esp. between the major cities, is pretty easy, but Texas is big. If you were to drive from Houston to L.A., you would drive over half the trip inside Texas. El Paso is just past the mid-point. A drive from San Antonio to Dallas is about six hours. To combat these distances, Texans have taken to the air. Southwest Airlines, Continental Airlines, and American Airlines are ALL headquartered in Texas. Flying is a big part of our economy, and a big cog in the intrastate travel wheel. Security checks (which I don't begrudge. WE NEED THEM) will add, at least for now, about three hours to the flying experience. One can drive from Houston to Dallas in that amount of time, so flying NOW TAKES LONGER THAN DRIVING. If you don't drive, or don't want to drive, then your only other option now is to take a bus. Texas has no interurban train service, except some limited trains in the Dallas/Fort Worth area. Each time high speed, interurban train service is proposed, it gets shot down by the airline lobby (who has lots of influence; it's no mistake that three major airlines are based here). I think the time is nigh for renewed development in the rail industry.
