STIFFY,
You'll definitely have access to the corral and pretty much any area in the pits or around the track. In the US, we're all "Presidents" of the Cobra Club. The real answer is we're not too organized.
Maybe someone has a new Bay Area Cobra Club or NorCal Cobra Club hat that they can bring to the track and trade for an Aussie Cobra club hat.
Looking forward to the event.
