I ski recreactionally at Parker and Havasu. I have not skiied the course in a while since you can't find many out here other than Canyon Lake or throught the Ski Clubs at Newberry and Corona.
I had heard that for a while someone was setting up a course in Newport Harbor. Just rumors though.
Have you tried any of the lakes in Bakersfield??
There is a private lake about 10 minutes from my house, but I have yet to meet anyone that lives there.
