Actually, putting Whiby Festival into a 3 year search only gets 2 threads, putting Whitby finds over 40, and more than half of them are about some aspect of the festival week at the end of August.

What sort of festival are you looking for. I prefer Whitby because it concentrates on the traditional with workshops and opportunities to learn, dance, play, sing. Some festivals are more slanted towards concerts and 'big names'.
