Mike,
It was, I think, you that photo-shopped sand into the grass bunker at Huntercombe (which, by the way, is not 30 yarsd from the green, that was false info when Bill mistook it for a different hole at Huntercombe). Your suggestion was that, for various reasons, including contrast, sand would improve that hole. None of those who have played the hole agree. My point is that without experiencing entire courses without bunkers and the use of these very distinctive humps and hollows, it's impossible to know whether they work or not.
