Heres a suggestion....

Contact Nick, the owner of Draxas and see when his next track day at willow springs is.
Last time Johnny and i went it was only about 100 bucks ( i think).
We got to spend all day at the track. A total of about 50 cars showed up...all diffrent makes and models (spec miatas were sweet).
But honestly, that might be the best way to go...Last time we tried to get an event like this going, we couldn't get more than 8 people so we canceled the event.
or check out
www.RedlineTrackEvents.com thats how Nick sets it up.....oh i was just on the site...Aug 27th...My Birthday, is the next even. 110.00$$$ and it gives you a list of the personal equipment you will need to bring.
