Open Water Swim Clinic in CA?

Does anyone know of any good open water swim clinics in California?

It occured me that I've never really swam in the ocean :o and if I hope to do a couple ocean swim triathlon's in 2008, then I might want to spend some time in 2007 learning to swim in the ocean. :)

The LA Tri Club has clinics, usually around Santa Monica or Redondo Beach. I don't know if you're ever that far south. Their Ocean 101 on Wednesdays is pretty cool.

Perhaps there is a similar club in Central CA?
