Ah.. but you do know you want to AX.. and you do know with whom it will be. If a PCA region, they likely have a website and a link to their rules/classes and some general AX information that would at least make you a smarter noob! (we were all noobs once)
Some clubs prefer (require) preregistration for instance, or offer a price discount to preregister.
You might want to make sure you put some extra air in your tires (some would suggest maybe 5psi more than "stock" to begin with). May want to bring a cooler and some food since sometimes large, open parking lots don't have their own food services. If hot, bring extra water, and a hat. Realize that there will be times you will have a work assignment and need to shag fallen cones, so be ready to run.
Either way, enjoy yourself and have some fun!
Is this the event?
