Many sites are available on the web.
Here is one you might find interesting from Sports Car Digest.
Monterey Motorsports Reunion 2012 - Shelby Cobra Race.
Many pictures are available. It is stated within the article that the Nor-Cal Shelby Club had 315 cars in attendance. Great job!
Good magazine - hopefully this link will take you to other articles in the magazine.
Feel free to post other article you find on the event.
