Well, the Portal gives a rating for accessibility, but I'm not sure quite how useful it is as it's just a mark out of 5, I think, usually without any detail at all.
I usually try to specifically mention accessibility in my fieldnotes nowadays, but I've not done many fieldnotes for Aberdeenshire, as a cuppla years ago I just stuck up the photies to clear a good few years worth that I'd never been able to post.
I seem to remember that most of the 'Hollywood' sites, like Easter Aquhorthies (sp?!), Loanhead of Daviot, Midmar Kirk & Culler(l)ie are pretty good tho. I'll tryta find time to give it some thought, tho I know that quite a few are difficult, including quite a few of those I've recommended to Harv....
love
