peaceful wild camping
Buck Palace?
Yes. There were a few cases of backpackers climbing the wall late at night and getting kicked out early in the morning with little more than a shouting at to not trespass. I can't find any online news articles for it though (would probably have to be an archive from pre-newspapers on web days) and it was a more innocent age (I remember it so probably late 80s or 90s).
There is this article about the 2007 change to make it illegal and not just trespass: http://news.bbc.co.uk/1/hi/uk/6492003.stm
