I really don't think we will ever see sprint cars again on a mile. USAC stopped running sprints on mile long tracks after Leon Thickston's son, Jeff was killed coming out of turn four at the Indiana State Fairgrounds. It was a really sad day and I was there sitting with my parents in the grandstand. Its also sad that sprint cars without wings will not run again on miles. I grew up watching my dad's Helliguass Offy running with IMCA and dad always thought sprint cars were only to run on miles and half miles and never on quarter miles.
