In reply to Kevin Avery - UKC:
There are degrees of secrecy, are there not?
Slipstones has been in published guidebooks certainly since the 1985 "brown" North of England guide, and on the web in several places. This latest article says little that is not said elsewhere.
I don't think this article will make much difference: those of us who live near enough to visit on an afternoon or evening will continue so to do, occasionally people will visit for a day from further afield.
There are degrees of trashing, too: it is less trashed than Brimham (or, I guess, Almscliffe, although it is a long time since I was there), but certainly more trashed than when I first visited twenty years ago.
