My brother is an old-time and all-around great folkie and lives in Placerville, not too terribly far away. Do you have transportation?
He's lived in the central Sierra foothills area for 30 years, so I'm sure he would have other contacts as well. PM me for a phone number, or if you'd like me to call him for you (sorry, he's also an old timer in the lifestyle sense and is therefore without e-mail).
