Not sure if the owner of the series and owner of Road ATL is still the same, but this is a race that should be at the other RA, Road America. Much more "Petite LeMans".......half the size, long straights, and a better ability to handle the volume of cars on the track.
Yes, they are the same. But it's not Doc Panoz, it's NASCAR and the France families other companies. Part of the fun of Petite is dealing with Road Atlanta.
