Sarmo-
If you want to particpate, just show up and people will let you know what to do (if you ask). No need to participate if you don't want to, but plenty of people, including myself, have chosen to participate in an Autocross before actually seeing one. New this year, there is a "weekend membership" for people who are not "full memebers" but want to participate, but it does count towards an annual membership at a discount.
I remember some of the coverage on the C&D event at (then) IRP, but I was not there. I did live in Indy at the time and I think it was earlier in the year that I helped out with a "Rotary Revolution" event at IRP. Chuck (Black 05 STi) was there, in an RX3, but I am not sure if he frequents this forum now. He will be at Sunday's event sporting various stickers, including Team Awesome Sauce.
Go TEAM.RIDE!!!!
