Having been to Brimham rocks a few times, I can attest to it's status as beauty spot, for me it is the best place in Yorkshire. Naturally I am appalled at the needless destruction of something so lovely, Brimham rocks is now ever so slightly not as good as it once was.
And yet, I've been mindless on occasion, I've rolled rocks down hills and watched with fascination at my handiwork. Hasn't anyone else been so bored they wanted to watch a rock explode. For some, the world isn't a very interesting place, they don't watch with interest as a bird flies by, they don't see shapes in clouds, and the certainly don't wonder about the nature of the universe. In all likelihood they wont ever get why everyone is telling them off.

Ps it's good to see that so many complainers have actually been to Brimham rocks taken photos and shared them for all to wonder at.
