Al R,
I'll be at Flamborough Head later in the week. It's a nice thought to put the memorial up there. The headland is also home to a memorial to one John Paul Jones (that's US Navy, not the singer) and one of the worse access roads in the country! It's a bit of a bleak place at the best of times and I can't see much traffic getting out there.
Problem is, of course, the memorial would never be in the right place! Someone would always have a better and more historical claim to it.
