Thanks Moth. I think you might well be right there, you cleverclogs. It's got a kind of bite out of the top of the stone hasn't it. The other stones looked so big though but I guess the big trees are a clue too? It's a long time since I was there. I like the Goldsworthy-esque floating flowers and the poles too. And No-One can wave their fingers about like Mr C. Ah happy days.
