I am having a hard time meeting other vegetarians in SW Montana. I was thinking about starting a group where I live and wonder if anyone has some suggestions to organize it?
Is there a college around? Or a coffeehouse? Health food store? Try posting flyers.
Those groups are difficult to get going, I know from experience.
I have a friend who lives in MO and another from there. From what I hear I understand how it can be a challenge. Have you tried meetup.com? Describe what kinds of things you have available to you. I know some areas are urban while others are very, very rural.
Universities would also be a good bet as Michael said.
