If you are interested in culture and music at all, you should definitely check out a dance in Cape Breton. Mabou on Saturday night is a famous one with a lot of locals, there's one in East Margaree (I think so anyway) at the Fire Hall, not sure what night it is but it's also really popular.

That's in West Mabou, for the record.

Pictures from my last trip to the Maritimes, if you are interested.
