One way to do it would be to start a group yourself. Whether it's a HN meetup, coffee house coders or Lean Startup circle all you need is to start a Facebook page and perhaps a meetup.com account.

Don't get discouraged if only one or two people show up at first. The first year is always the hardest for a group. The important thing is to provide value. If you do that word will spread and the group will grow.
