Chattanooga, TN (relocating to this city soon). They're all in the same area.
There is also BJJ and MMA in the area, which I'm starting to also consider.
If you're looking for the old-school Gracie Jiu-Jitsu which includes the stand-up/self-defense aspects, you may be in luck.Fortunately it does look like you have some good options for both BJJ and MMA in the area. I'd visit as many schools as you can to see which one seems to fit best for you.
This school: Jiu Jitsu & Self Defense Classes Chattanooga Martial Arts School has an instructor ranked under Pedro Sauer, who is old school GJJ.
This school: Kioto BJJ Chattanooga has an instructor ranked under Francisco Mansur, who is really old school GJJ.
I'm not personally familiar with either of the schools, so check them out for yourself, but they both definitely come from a self-defense oriented GJJ lineage.
