What makes this series great is that (untill recent times) the format hasn't changed a lot.

I think people like seeing 100 laps. It gives plenty of time for things to happen. Part of the excitement is who's tires are going to go bad, who is going to run out of fuel, the strategy involved with racing harder or when to make a move. Who can get something going in another groove. Roll cages, drivers nets, arm and head restraints and better seats were great changes for safetys sake. The cars are perfect for the type of racing they were designed for.

I think to a degree since the DuQuoin track is raced on rarely through the year you probably have to deal with what you are given. I don't know about weather in DuQuoin but we have had about 2 straight months of 90+ degree weather. That may have an impact the track also compared to conditions some other years.
