Finding Good Developers in Los Angeles?

I'm part of a CTO group that meets once a month to discuss various topics. About 18 months ago, the entire group began to mention that they were having more difficulty finding good developers. Since then it has become much harder to find people and while we are talking about hiring relatively small numbers of people, the typical sources of candidates don't seem to be working.

I personally believe that there are lots and lots of good developers working inside of organizations who would love to work on the interesting projects that we work on all the time, yet they aren't out actively looking, so it's almost impossible to find them. If anyone has ideas on how to reach into to find candidates or other ways to find good people, I would love to hear it.
