Well, I didn't know anyone who knit here, either. I didn't know of a knitting group. So, I started one. I found some gals online who live up to 45 miles away, and believe you me they ARE willing to commute. We take turns meeting in different places, so that way no one is driving very far every meeting.
Try posting flyers in your area...it works. Church, school, craft shops, book stores, those are all great places.
