Wasn't there a fatality on the Springfield mile in a modified a few years ago?
Evansville driver Cliff Johns was fatally injured at Springfield in a sprint car on Oct. 7, 1973 and Doc Dawson was also lost there in a sprint car, in 1978 I believe. Jeff Thickstun perished in a sprint car at the Indy mile, 1983, I believe.
Some cars are not suited to be run on a mile track because of the inherent danger.
