Hey Paul, it was held at Calero lake in San Jose. Here is a link to a discussion from last year: http://www.wakeworld.com/MB/Discus/messages/65919/175383.html?1088186854
I'm with you, I know there have to be literally hundreds of simple grass roots events, or even just off shoots of a wakeboard event. Maybe we need to offer a reward for any info leading to the discovery of an actual event?
We did just come back from one held in AZ by the AWA, Liquid Force and Century Marine - they were great people and it was a very fun, informal event. I'd go again if tey decided to hold another one.
