The only year I attended Ancient Ways (might have been 85-87, can't remember) there was a bunch of young men from the nearby town who invaded the site -- I was for some reason the only volunteer on duty for security and someone handed me a broadsword and a lantern (it was around 10 PM) and I went after them. I may have been wearing clothes, too, but in any case they saw me and ran off in the direction of the entry road.
