Hey Sean,
I spent a week at Swannanoa a few summers back. I was there for dance week, which ran concurrently with dulcimer week. I must echo your sentiments, my experience there was just perfect. Beautiful setting, friendly folks, great musicians. I just had a blast. Sadly, dance week was not well attended and they have stopped doing it. They now do something like community dance week, but it is not quite the same. The dulcimer people, both staff and students were incredible. I play flute, whistle, tenor banjo and didjeridu. They were so welcoming, no matter what I chose to play. I am glad you had a great experience, and I would heartily reccommend that week to any dulcimer players out there.
