What's the best way for me to find other parents to start a homeschool with?

I want to homeschool my kids. I’m not a religious freak, just a disillusioned public school teacher who is unhappy with the direction of public education in California. I want to get together with a small group of parents who have the same educational goals as me, but I’m having trouble figuring out the best forum to find these other parents. Suggestions?
