I would not think it was my right or it was ok because "I know better than 99% of the general public", or that I have special dispensation.
Not at all. I would feel guilt.
But it goes beyond that, for me. It really does. But I cannot defend it.
This is why its a dilemma for me.
I suppose I could attempt a defence by saying that if 70,000 people did what I would do, exactly, sit on a modern gravel floor in one the houses, there would be no damage. But I realise I'm on difficult ground. (I don't mean the gravel would be uncomfortable :) )
Also you seem to imply I'm being dishonest to myself for claiming I wouldn't do it. But I'm far from perfect and I really don't think I would. I think I could bear to hold myself back. It wouldn't be too much of a dilemma.
Human beings made these places, and human beings are interested in them now, still. We are all clinging to a huge rock in an unfathomable universe.
In 40 years I won't be here (probably less).
If I am responsible for myself (theres not enough of this these days) and ensure I do no damage, then, yes, I simply MUST experience something as wonderful as one of those houses.
And the houses will still be there in 4000 years time if I treat them well whilst experiencing them.
Maybe that is an impossibility at Silbury Hill.
I can't resolve the argument to my satisfaction, and I know your opinion is the correct one in my heart, but I feel theres more to be explored in the detail.
