Sac State has a wakeboard team that rides behind a brand new super air natique 210 3 days a week (M,W,F) from 9-3 during the semester. They have a driver so all they have to do is show up at the dock and get on and ride and can take off whenever. They also have meetings on thursday nights and do group activities and weekend trips. Check it out at http://www.sacstateaquaticcenter.com/Body_wakeboardteam.asp
but some of the information is old.
Chico state has a really good club right now and they have a web site.
cal poly's club is called "CCAW" central coast assosiation of wakeboarders and I know they have a facebook.
hope this helps.
