There are several tracks here in the south that grudge races are regularly run at. The more well-known local ones are:
Headhunter Dragway - Eatonton - www.headhunterdragway.com
Phenix Dragstrip - Phenix City - PhenixDragStrip;PhenixMotorsports,PhenixCityDragSt rip
Twiggs / Macon National Drag - Macon National Dragway
Carolina Dragway / House of Hook (HOH) - Carolina Dragway - The House Of Hook - Jackson SC
There are also large events held at Silver Dollar (GA), SGMP (GA), and Steele (AL). Let me be clear though - the slowest class generally is bracket, and they run as slow as 7.50. The heads up classes run from low 4's up to mid 6's in the 1/8. Anything else is bracket at the bigger races.
There are also some small hole-in-the-wall tracks like Camp Hill (AL), LaGrange (GA), and Brainerd (GA), that might be more the action that you might be looking for.
I gave you a link earlier to Carolina Grudge. You should familiarize yourself with the local scene, so you know who can help you setup your races.
