Unfortunately it takes a track with major draw at the right time of the year to even think of pulling in numbers from everywhere. Indy, Road America, COTA and Laguna to me are the only places that can do what needs to be done for one event. Mid Ohio, Road Atlanta, Thunderhill, Infenion, Heartland Park, Daytona, The Ridge, Barber, your favorite, ect are all great places but it’s gotta be brand new awesome or a track with serious racing history. People in general really don’t travel much farther than 10 hours, it’s gotta be good. The average racer just won’t do it.
