I believe this is purely a business decision... a decision based upon some people will stay home and food sales will be down during the heat. I know this decision is one that alot of folks don't like but I can at least respect the tracks decision to not risk a financial loss.

Remove yourself as a fan or competitor and look at it as if you are the business owner.... Is the risk worth the reward?

Sprint cars don't like going upside down... neither do the promoters.
