Ask HN: How do I find nearby hackathons?

No interest in sparking this debate again, but as background, I am teaching myself to code. I've been at it a couple months and would like to meet people more experienced than I and see what a hackathon is like. The trouble is, I'm struggling to find good resources on where any are. I'm in the Bay Area, so I know they're around, I just don't have a go-to site that keeps a good listing. Does such a thing exist?

Any help on finding some good Bay Area hackathons would be most appreciated.
