I didn't see it in the article but this was a CSRA (Central States Racing Association) race. AAA had dropped out of racing at the end of 1941 because of the war but other groups continued to race until sometime in July in 1942 when the government stopped all racing. Chitwood ended up being the 1942 CSRA champion. Drivers like Chitwood and Ted Horn won big car championships in both AAA and CSRA because there were working agreements between the two groups since they both wanted the biggest name drivers for their races.
