I plan to be there.

Helmets: Most events require a snell M2000 or SA2000 rated helmet. full face or open face doesn't matter. DOT only rated helmet (cheapies) are not allowed. There should be a holographic label inside the helmet that Tech inspection will look for. Sometimes, loaner helmets are available at the event. Some snowmobile, atv, motorcycle helmets are M rated. You'll probably want to put 42/40 or 40/38 psi in your tires on that day.
