http://www.norcal-saac.org/news/COCOA-Willow2011.pdf This is the regular event scheduled by Lynn Park, the uncrowned King of the Cobras, out at Willow but as I understand on the regular track. There is another event later in the month at the Streets of Willow which is a less high speed track next door. Incidentally Willow is the track where the Cobra,Shelby Mustang and GT40 were all tested in the original Shelby American days. At any rate this is a good event to see genuine Cobras, replica Cobra, Shelbys, Bosses, Ford GTs (originals and the '05-'06 variety) and such. If you go to that website it spells out the rules & requirements. We'll be there in our Cowboy Bob outfits... See ya on the trail...
