I'll answer that question with another question - have you ever taught in a classroom ?
My proselytising of the Knarsdale sites has the opposite effect to the one I intend. Instead of opening them to the public gaze my encouragement to yourselves - probably wasted breath - preserves their inaccessibility. Try 'England's Largest Sculpture' (verbatim), in Google, for more details.
I bother because it's what I do.
