That's nowhere near 'threatening' enough in todays world. Not a word about trespassing or it being illegal and of being presecuted. Why not?

That photo speaks volumes...

I can't believe nobody's suggested astroturf! Hard-wearing, looks like grass from a distance - the idiots can climb it all they like then, without ruining it for the rest of us! :D

Thanks for the link Nigel. I note the reference to "hundreds" of people climbing each year. I hadn't appreciated it was so many, I assumed (probably naively) that it was a few dozen. I've never seen anyone up there myself, but I've only ever been there (to Avebury) in the day and not that often. Have I underestimated the scale? Are we talking "mass climbing" in groups, or lots of solitary visits?

[Just curious, rather than going anywhere with this.]
