Back before USAC tried it's first of many unsuccessful suicide attempts
(removing the dirt from the champ car trail) the dirt miles were all SRO. The races mattered more to the casual fan because they could see someone who ran Indy , race on dirt. Also the fans knew if you were to win the title you had to race on dirt.

As for me there is no more beautiful sight in racing then a Champ dirt car on a mile. Poetry in motion.

Yeah , I know Kokomo is eight minutes away, but I wouldn't pass up a chance to see this at Duquoin.
