Houston
There's also Weiser, a 20 minute drive out of downtown houston. Single hard strip (good crosswind practise), friendly bunch but can be hard to find.
I did a night flight over downtown Houston, past the monument and did a T&G at Galveston. Key the mike on the ground frequency to activate the runway lights - cool!
Ellington was good, had a good eyeball at the F16s and got buffetted by their jetwash on the ground :-)
Flew over to San Antonio from Houston one day, just for the experience.
Have fun.
