There is more to it. D-37 has limited itself to 6 Grand Prix per year aka: "The Big Six Series". The Big Six operates as as a unique group within D-37 org. Last year the Catalina GP was a special exception and was a non-point paying D-37 GP.
Anyone want to point out Vinnie's link to the Big Six?? With Vinnie involved last year it was ok to discuss, with Vinnie out, it goes the way of USDR, Adalanto GP and the Race Around the Lake GP.
