I don't think of Ventura as Southern California. That's just me I guess, hey, I think Chatsworth is in Northern California too and trust me I'm not geographically challanged. I just think anything South of Malibu is Southern California and everything North of Malibu is Northern California.
Heck, I still waiting for Southern California to break off into it's own state. Well I can dream can't I. Likely not in my lifetime.
