wilco48 beat me to it. Yes, Martha Berry's college was once a natural place for that sort of thing, I would think, but may not be now. I haven't heard of much folk music interest coming from Berry College in the past 20 years. It's maybe 50 miles north of where I frequently stay with my friend so I might be able to go over there someday and ask at the archives in the library, which I am assuming they have.
