Thanks for the detailed explanation. I do understand the concept of HPDE, I just did not know what your Atlanta event was all about.
If I can get my drivetrain sorted out I will probably try a HPDE at Waterford or Gingerman raceway as a primer. I can probably get away with a set of pads and good brake fluid to get started.
It would be awesome to drop the wife off with my daughter in Chattanooga and go to your event and the dragon.
