What are the best VW/Porsche events to attend in California

I am planning a holiday in Calfornia in either May/June or September/October travelling from the United Kingdom and don't want miss the best events. What events do you recommend?

Matt - Besides the SOC event in Carlisle, Pennsylvania, in May, there isn't too much going on in SoCal in May/June for VW/Speedster stuff. However, here is a link to a website that lists all the other major car events in So. Calif through the year. Hope this helps...

Matt - just show up at Jim's house. The party never stops between May and October. You could show up at Vince's house too, but I wouldn't want to be responsible for that . . .
