Flew my wife into DFW a couple years ago for a fire fighting school hosted by the airport which allowed us to get the $135 landing fee waived

. Was allowed the privilege to put 5 miles of taxiing on my 8" tailwheel as they vectored me to the most remote runway from the only GA FBO on the field. To say DFW is not GA friendly is an understatement. I will say the controllers were courteous and handled me well.
AeroCountry (T31) was a nice spot I have been into to pick up an O-470 rebuilt by a nearby shop. Close to DFW and just underneath the Class Bravo. Staying low keeps you out of their hair.
The Texas Maule group (

I agree with Gunny; Life is too short to live in Dallas; get out more west if you can.
The scenery in Texas is not as spectacular as Alaska but you'll appreciate the improvement in roads, infrastructure, tax environment, etc. The western part of the state has numerous small mountain ranges and alpine forests to visit. New Mexico is fun and should be within your range of comfort being from Alaska. Lots of scenery and mountains there, too.
