The BMWCCA Alabama chapter is having a HPDE at Barber in Birmingham on July 24 and 25. I went last year and was very impressed. Registration hasn't started yet. http://www.albmwcca.org/

There is also a HPDE at Talladega Gran Prix Racetrack on March 14th. http://www.tgprace.com/
I can supply more info if needed.
