There are about as many reasons tracks close as there are closed tracks.

One reason that doesn't get much play is that no one wants to run them. For all the internet experts that know how it should be done the people who will step up and do it are few and far between.

Give you an example, when Joe and Steve Kosiski decided they'd had enough of operating I-80 Speedway in Nebraska they tried for two years to find someone to take it over so it remained a race track. They'd built it from the ground up after Sunset Speedway in Omaha closed. It was all newish and nice. It made money. Joe said in more than one interview that they were just tired of having to be there every night. He said it was easy for them to hire people to run their other businesses, but if he or Steve were not there on race nights the whole thing went sideways. They would have seller financed it. They would have stayed on as consultants. The only things that were not negotiable was the price as they had a standing offer for the property and the day they were going to be done operating it.

So where were all the people who know so much about how a race track should be ran? All they would have had to do was slot themselves in Joe's role, hire someone to replace Steve as the track prep guy, and take the money to the bank.
