Learning for localvores?

Ok... so i am considering going local, and I am trying to find some networking for support. I have looked at several websites, but of course they are geared toward their specific locale. I understand that. What I was wondering if anyone knows of a national directory in the US that can get me in touch of any local groups. I am in the Hampton Roads section of Southeastern VA and very close to the NC border, so a group in Northeastern NC would be fine.

Any suggestions or advice about making this leap?

I am still doing my homework, and am not planning to make the switch till Spring.
