Just a bit more:
Looking at the DFW AC site you will see that there are plenty of "car" hobby events in the DFW area. You might also want to look at the BMWCCA Lone Star Chapter site
. They are active in autocross, DE's, and tours. Depending on your interests, there is plenty going on: Several museums, symphony, ballet, plenty of live music (the University of North Texas in Denton has a huge music program). Then there's pretty much all the professional sports.
