I don't live in the California area, but I am a car show fanatic. My husband and I are working to develop a car show website if you are interested in finding car shows. It is still in its infancy, but it is getting a lot of momentum lately. In fact, I am getting behind logging car shows for the calendar because so many events are coming in.
Here is the site:
www.CarShowSource.com
It is nice to meet everyone!
