Like Tim I've made my peace with the loss of Whitehouses. I can only imagine that with so many holds destroyed (and they really were destroyed) that the remaining climbing would have been pretty limited, especially given the sandy nature of what remained. I know the right hand side was fairly untouched but let's face it that wasn't the bit most people spent time on. It's gutting obviously and it hurts to see it being further vandalised, but I'm not sure there's much more to be done.
Out of interest, you said a JCB was working there; did you try and speak to the driver at all?
