Got to be a relatively local person, why pick a little circle like that otherwise? If you want to make a proper impact, you want to go to stonehenge and dash clear of security whilst madly wielding your paintbrushes. (No please don't.)
Poor nine ladies, why does it get so little respect. I visited as a kid with my family, I dragged them up there and then there were a bunch of gits camping in it, I was so appalled. If it's not paint it's camp fires and litter. So depressing.
