It has happened before. I think a few years ago, maybe 2012 or 2013, there were several tracks that cancelled around this same time of the year. Late July or early August after sprintweek.
A few years ago we were headed to Bloomington Speedway when they cancelled due to heat. I griped and complained about it, and then stopped in Shoals to get gas, got out of the car and holy &@! Was it HOT!!!!! I poked my head back in the car and told my wife forget everything I said, it is too hot to be messing around at the track.
More of a business decision. Fewer and fewer fans are willing to sit through the heat to watch racing. Sure the track "can" run, but when the people don't show up the track takes it in the shorts. A business cannot willfully and knowingly open its doors and take a loss just to accommodate a select few hardcore supporters looking to get their speed fix.
It really sucks that society continues to progress into a "must always be comfortable" way of life. My grandfather never allowed an AC to be installed in his house. I bailed hay as a kid in full jeans and long sleeve shirts. Worked the fields detasseling. Got used to working in the heat so it never really bothers me so long as I can stay hydrated, but no one seems to have any endurance these days.
Unfortunately short track racing is not strong enough to change society and as long as society continues its push to the "fair weather" side of things, most tracks will have to bow to them in order to survive. Some places have enough of a hard core base to be able to get away running in adverse conditions, others do not. Sucks, but as they say, is what it is.
Bailing Hay was never the hard part, The hard part was stacking it in a very little ventilated loft. Also did three hour a day football practice finished off by a half mile run in full gear. But Im not 16 anymore either.
