I thought it was Mr Bog, Frances Pryor who thought of digging a bit deeper?
What I though was that the huge looking section of a circular feature that showed up on the geo-physics was dismissed as 'Frances thinks it's prehistoric'.
They also didn;t really find very much, just a pre-Roman Iron age settlement that happened to be on Anglesey. I think I get a bot over exited when Time Team do something that I'm really interested in and almost always end up dissapointed.
I really enjoyed the one last week at the school...
