Have only just spotted this thread.
"EH had a Peer group meeting about it late last year which was so productive even the Hertigae Action chairman didn't feel the need to raise a question."
Not so. He did. Several.
He was the only non-archaeologist in a room full of several hundred of them so he did his limited best, thanks.
Heritage Action will post a very long statement on Britarch this week.
If it's thought to display a misunderstanding of the situation, or a lack of research, or realism, or statements not in Silbury's interests, or an unwillingness to stand up against the establishment, or an inability to take them on in the technical details or any sort of apathy or lack of will, then that will be the time to say so.
Day to day management of the hill is awful, as we all know, but that and fences and notices and rabbits and dancing druids aren't the main point. In comparison to that they're mere here-today-gone-tomorrow bits of knockabout and tittle-tattle. I refuse to do anything that diverts from the main issue, which isn't the delay any more, it's the scale of the damage that's going to be done during repairs. That scale is an optional matter it seems, and you can guess which option our friends seem to be actively promoting.
That's it Pete. Don't ask us to run a rabbits and druids page. It's not going to happen.
