Not a fan of the square tail tank myself but it wasn't a USAC event and if the Rumble promoters want to let them run square tank that is their decision. I'm sure there a few cars at Ft. Wayne that wouldn't fit USAC rules. Be thankful there is some open wheel racing in December when there is a foot or more snow on the ground in parts of Indiana. Wish they would run DuQuion more than once in the winter time.
