I'm sorry about the bulldozers. I didn't realise that others also had difficulties with blind professionals. The process of loss is similar whether it is a five thousand year old burial mound, a one thousand year old Norse hut or a one hundred year old urban heath landscape. My cliche is that conservation is about 'making things last longer'. But human culture is a hungry monster gobbling up everything in its path.

The first rule of First Aid also applies to conservation - don't put your own health in jeopardy. In the context of saving butterflies and megaliths this means 'don't burn out'. (You have seen Pirates of the Caribbean?) There's a large icesheet in the Arctic just broken up - has anyone heard about it ? (Of course not !)

The local government archaeologists have an association - which I call ALGAE. They must have an annual conference somewhere. Maybe there are seminars...
