If y'all are looking for groups here's what I know exists in NC...
First off, there's a statewide NC Poly email list-serve. The homepage with info is at http://www.ncpoly.org
Subscribe to the list and you'll get regular info from them.
On that list, they announce a group that meets very regularly (every Friday for a coffee social, and on the third Sunday of the month for discussion group) in Durham, called Triangle Polyamory Network.
The listserve also announces a small get-together of folks who meet every other Thursday in the Burlington area.
And occasionally, they'll announce a meeting or gathering of folks elsewhere such as Charlotte, etc.
For those in the western third of the state, you have another group (WNC Poly) that meets monthly in Asheville: http://www.wnc-poly.org/
Hope that helps everyone here!
