Not sure about Saturday (memory has faded) since I didn't go there back then. Was I-55 called something different then? It would have been in the late 50's-early 60's time frame. St. Charles is correct for the Sunday night show though. A tough grind for these guys racing three days each weekend at three different tracks. They didn't have multiply cars so if you were torn up you had to go home and put it back together again. Great times for sure.

I believe that they competed for an overall championship for the three tracks. Forgot to mention in the original post that the flagman was on the inside of the track as well as the announcer and scoring folks as they are today. Very tight quarters for sure. Also, I love your avatar. Great looking race car from back in the day.
