For those of you that may find yourselves in Sonoma Valley, CA thru February, this may be interesting: The Sonoma Valley Olive Festival. It apparently has a strong emphasis on olive oil.
Here's the link:

I've never been. In fact, I just saw a reference to this in the Sacramento Bee this Sunday but it sounds yummy!
