Oracle - the PCA Wildrose Chapter organizes a few events over the year at Race City. These things are great balls of fun and pretty cheap to participate in.
I recommend that you join the club (also pretty darn cheap) - that gets you on email distribution for upcoming events like autox as well as events going on in other chapters. The club also frequently announces autox activities of other clubs that are going on at Race City. Membership in PCA also gets you a discount on autox entrance fees as well as cool stuff like the monthly magazine and chapter newsletter.
