I saw a message on FB from the track owner and he said he decided last Friday to cut his losses and suspend the season. He was in the process of contacting the different entities that had events scheduled when the news leaked out. He said a formal announcement will be made on Wednesday.
I copied this from his FB page:
On Friday, May 29 at 2:30 pm (EST), I came to the realization that with 83% of my revenue lost for the year, that it no longer made financial sense to attempt to open and run the risk of losing anymore money for the year. Instead, I thought, I need to cover up and live to fight another day. With my path now clear, I began the process of making calls to the parties who needed to know in advance of an announcement. Unfortunately, my decision was leaked and blew up this morning. I apologize to so many that found out through a rumor piece instead of a message directly from me. A formal announcement will be made on Wednesday.
