I remember that 600 quite well. I was the Operations Manager for the radio station that broadcast NASCAR. We had also aired the Indy 500 earlier that day. In the days before automation, I had to run our local commercial breaks for the broadcasts. So, my day that day started at 9:30 (the Indy 500 prerace started at 10 a.m.)....by the time the 600 post race was over, I had put in a 16 hour day. I remember alerting our payroll person that when she saw those hours on my time sheet what they were for.
