Have you visited the Bay Area Cobra weekly breakfast or the Northern Cal monthly meetings? Cobras on the Coast this weekend? I would also guess that there will be quite a few cobras at the Livermore show Sept 25. I would rather check out the Hooters meet coming up in the South Bay Sept 25.
Always a few cobras at the Good Guys show in Pleasanton.
