Dallas has 4-5 decent tracks within a four-hour drive, and MSR in Cresson is my favorite. The others are Hallett, MSR Houston, COTA and Eagles Canyon (last on the list but new owners are supposed to be updating). MSR In Cresson has two configurations, the older 1.7 which is great in both directions, and the 3.1 which is run CCW. Plenty of weekend HPDE opportunities if you don't want to become a member immediately.
Feel free to PM me or respond here if you have questions. Search YouTube for vids - you watched one of mine last week.
