The event is still open if people want autox on sunday. You don't have to have a bmw to participate in the autox. You do get a discount if you are a BMW CCA member. Xnoodles, my husband and i will be there autoxing. You can register online at: http://www.peachtreebmwcca.org/ptAX_index.asp
Do you have to pay in advance for this, or is it like the SCCA events where you can register and if you don't go, it doesn't cost you anything?
When you register you have to pay. They have everything set up on paypal. I don't know if they do refunds if you don't show up. I know BMW cca likes to keep the number of cars down so they prefer you to register online. You can always try showing up on sunday morning but i don't know if they will have anymore spots left.
Of course brian is going, he's my husband! Unless you are running the in autox you don't have to show up early in the morning.
