We (my husband and I) are always looking for friends... We're in the Portland area.
There are a lot of poly social groups in the PNW, actually. You might check out meetup.com to see if there is one in your area. We've made a few friends that way.
Seattle has a really large poly population, as does Portland. Everywhere in between has a smattering as well, but obviously smaller towns make it more difficult to find a group.
