Agree strongly with all your points - the saintly Joanna may well be the best bet.
I don't think people know what the NT are up to here and public opinion will definitely view their "law" as taking the pi&&.

BTW - I didn't get to see your display in London but the book looks fantastic. As I live but a stones throw away from the Peak District please let me know when you come to publishing as I'll be in line for a copy!

Hope to see a copy soon :-)
