Putting Palin aside for one moment, after all she's got a long hike back to Alaska, and returning to the subject - like googling the 'oldest stone circle in Great Britain'

Apparently Castlerigg makes a play for the title, and it was one of the first monuments to be scheduled in 1883. It was geophs'd in 1985 but the report still has'nt manifested itself!
