How many folk festivals are there out there which place a distinct emphasis on local regional folk arts, music and artists?
I'd like to know why I should travel a hundred miles to experience something regionally unique and distinctive? (I don't mean something like a generic "Irish" or "Scottish" festival, for both countries contain distinct regions within them.)

I'm sure there are the folk festival equivalent of regional food fairs, which folk festivals are dedicated to presenting local regional folk arts and music? Where are the Arbroath Smokies and Salt Marsh Lamb of folk festivals to be found?

There must be a great number of local specialities I'm sure, but which ones are really special to you, and why?
