Greg Weld at (I believe) Winchester, Indiana in 1965. The #9 car in the background was driven most of that year by Johnny Rutherford who ended up as the USAC champion.
Very similar photo showing Weld at IRP where, as you state, he won the 100 lap feature in 1965. But the the original posted photo showing the tall covered grandstand is Winchester. IRP has never had a covered grandstand. That's for posting the IRP photo as I had never seen that one either!!!
Thanks J. I am familiar with that last pic type.What I'd call a hard top,but that fast back type style I never knew.
