From an email I put together for a friend coming to Texas, I thought it would help fellow folks with an itch to get their car on the track where it belongs! 
Some of the clubs in Texas to drive with, on their websites you will often find the information about the local tracks. They just do HPDEs at this time (fun track days, no time trials) --
The Drivers Edge
Another is Apex Driving Academy
NASA: #DRIVENASA - Texas Region | We Drive Harder! - Welcome to Texas Region for the National Auto Sport Association. Here you can find all the information necessary to get on track at our events. (HPDE/TimeTrial/Races)
For two auto-x clubs check out: Equipe Rapide SCC - Autocross club - Texas - News
There is also a lot of PCA and BMWCA and of course SCCA stuff in our area...
