Not in the Valley? How do you find co-founders?

It's pretty clear that if you are in Silicon Valley and are moderately good about networking there's an "established" (if I may use that word) path to finding co-founders for a startup. If you came out of a school such as Stanford a lot of your search may have actually been "automagic" in the relationships you built while at school.

But, say that you don't live in the Valley. And, say that you are a relatively new Internet entrepreneur in a market like Los Angeles. You are not 20-something, so no school relationships to bank on.

How do you find co-founders for a venture?

Please don't say "move to the Valley"! :)
