Digi,
Since you indicate that you live in the Southeast, this website should prove helpful -

Click on Calendar and you'll see a lot of choices. I've done two weekends at Road Atlanta with the BMWCCA, and a weekend at Roebling Road (Savannah) with Seat-Time. I would recommend both whole heartedly. You need to do your homework ahead of time, though, because the events can sell out quickly so you need to get in the loop as to when to register.
One warning - it's incredibly addictive!
