This is an annual festival that I have not been to,  but I know number of the instructors; a family gathering is keeping me away this year. 

This year Joe and Chris Steiner, Shari Wilf, Bill Schilling, and others.  Along with mountain dulcimer courses, there will be classes in hammered dulcimer,  penny whistle,  singing and more. Scene

Schedule is on their Facebok page.
