You don't say what experience you have or what contact you have had with your local folk scene.

Assuming that you haven't had much contact with other musicians then start playing for local morris sides and get along to any session that will let you in.

If you are just the only young musician in the area, which would surprise me as I can think of quite a few second generation folkies in their teens and twenties then get along to a few festivals or a Folkworks summer school.
