which site? The Whiteleaf? I've been through Princes Ris loads of times, and never noticed (the cross is pretty badly grown over, but there's a bid in to sort it out ...)
In fact, I was right on top of it, and never noticed the cross, until a curious gibbonnette strayed off the path ...
Wain Hill and the Bledlow cross are even stranger, if such a thing is poss ... might nip up tonight ...
