"September 30th's Autocross is going to be a little different than usual-- we will still be doing our Full Day (Understanding Vehicle Dynamics-$250-8am to 5pm) and our Open Day (Unlimited Laps-$125-12pm to 5pm) like always, but we will also be offering pay-by-lap, as an Open House Event. The cost per lap will be $10 and is open to anyone. So it's your choice: Full Day, Open Day, or Pay-by-Lap,
bu...t no matter what you choose we will be meeting at the back gate instead of the office parking lot. We'll have a GPs location up soon for those of you unfamiliar with our location, as well as signs pointing you in the right direction on the day of the event. So spread the word and tell your friends who have been wanting to try Autocrossing!! Hope to see everyone there!! Oh and if you plan on doing the Pay-by-Lap, help us out and bring lots of $10s... it'll be easier and make the day go by quicker if we don't have to give change out at the starting gate!!! Thanks!!"
