I'm not saying we shouldn't visit places like those and walk there, sit amongst them, picnic, chat, paint, whatever. That's the very thing we all love doing. And there's minimal harm because there aren't 70,000 visitors a year doing the same thing, maybe not even 70. But some places require us to put our personal whims aside and behave in the long term interests of the site and the people in the future that might want to see their inheritance too. I don't see that's so much to ask.
