  • Feb 21, 8:30 PM - X30 Senior is now sold out and X30 Junior is not far behind.  In order for us to justify expanding one of the two classes it's imperative you submit a registration to get on the Waitlist. Stay tuned to this website and our Facebook for the latest updates.
  • Feb 20, 10:00 AM - ATTN: X30 JR & SR DriversAs we near capacity in both classes we might again have to make the hard decision on which class to split if any. We will have about 30 minutes less daylight than Florida so the chances of magically splitting both classes is slim. The only way to guarantee your spot is to enter NOW to avoid being put on the waitlist of a class we can't split.
