Does anyone recall the year that the IROC series ran a group of qualifying races to determine the final 12? I believe that they ran the Indy cars guys as a group, NASCAR guys as a group, and F1/IMSA guys as a group and took the top 4 "qualifiers" from each. Does this ring a bell?
The reason I ask is that I think IROC needs to look back to re-invent itself. Run the races in Nov-Jan during the off-season so you could get some full fledged participation from every discipline. Throw in a road course or two. Give us diehard fans something to watch. Anyone else have a brilliant idea?
