I too, would like to know exactly who was the prime instigator of the total separation of dirt racing and pavement/road course racing way back in those days. Gurney's holy white papers have been mentioned and the Cooper Climax have shouldered some blame but no specific person or group has been identified.

The names traditionally most mentioned in this regard are Penske and Patrick who undoubtedly applied more than their share of pressure to abandon dirt racing as a viable part of championship auto racing.

It would be interesting to learn the real story in it's entirety.
