There was someone up there yesterday lunchtime as I drove past too!
BTW the stiles have gone.
It's pretty constant isn't it? and that's a start regarding the stile, I last saw them [to be honest - used it] in June, Are you sure? [i'm sure you are though] i'm talking about the stile right by Silbury [Avebury side], that guy you took a photo of the other day looked a little old to be jumping over the fences, but you should know been so close.
