Followed BNs link to the Prehistoric Society webpage... n' it looks interesting. By the looks of the ariel pic, I don't hold out much hope of finding much on the ground.

Still, theres lots of barrow n' a nice bit of coast nearby, so a trip there wouldn't be a complete loss. If the weather isn't too bad this weekend, I may take a bit of an amble out there.

I think I vaguely know the area. It doesn't seem far from the visitor's centre at Cley.
