One of the more well-known ones fell over a couple years back. It was one that they cut a hole through for the road, back in the day. If they had known it was over 2,000 years old back then, I wonder if they would have defiled it that way.
It would certainly be interesting to climb one. A bit unnerving, I bet.
yes, you'd have to be a rock climber I think, I have no idea how they get up there though. I didn't know about the one with the road through it, I wonder if that's what killed it?
