We were over there last year and did'nt find anywhere to fly till we got to the Mississippi gulf coast,started off in Dallas, then down to Houston. Any airfields we found did'nt have FBO's, just private aircraft, loads of helicopters, presume something to do with the oil industry.
We had intended staying in Texas, but decided in the end to head east in the hope of finding somewhere more to our liking.Hope you have a bit more luck finding somewhere than we did.
