Terry Barkley, a True 10.5W racer, lost control of his Nova, crossed the center line, and struck the retaining wall head-on. The car burst into flames, and the spilled fluids set parts of the track ablaze.
The accident not only destroyed the classic Chevrolet but also did a fair amount of damage to the track. Race officials determined the damage could be repaired but would require a significant amount of downtime. When it became apparent an overnight fix was not doable, the decision was made to race to half-track.
