Yes, last year it was, MSCS called me early in the year and said they wouldn't co sanction this event with USAC anymore and their reason was they don't like to co sanction, even though they do it at haubstat multiple times, I told them that was fine, and then they later added a show against us at haubstat. That's when I cancelled any events with the MSCS, end of story.
Good luck to all!
