I think we have them over a barrel.

"English Heritage now carries £5 million Third Party Liability (PLI) Insurance Cover for the risks associated with visitors to our sites...."

... except at Silbury, where they've invalidated their cover with stunning clarity and are wide open to civil claims not to mention a maladministration ruling by the Ombudsman.

I'm torn between dropping a line to their Corporate Communications Manager [email protected], who I am sure would go absolutely ballistic, or posting some more notices to see if they're stupid enough to do it again.

I think I'll put some more notices up, although since I suspect they look at this site, I reckon they'll have their own put up by the end of the week. So it's up to you chaps - leave my notices alone, or replace them with adequate ones of your own, or watch me tell the boss what you've been doing.
