I was told by the superintendent and manager of The Vintage here in Australia that Greg Norman makes an annual visit to check on it, such is his fondness for the place.
I take it that is a very long way from common?
It might also help that some of his wines are grown in nearby vineyards...
Scott, I think the proximity to Ellerston may have more to do with visits to The Vintage, rather than the attraction of any of the wines emanating from The Hunter.
It's interesting you mention Norman / Harrison, as Greg Norman, for all his foibles, and his position below the top tier of world wide course architects, was perhaps the inspiration for this thread.
I once saw him play 10 holes of his Moonah course at The National around 18 months after opening. He was followed by a large contingent of members, and club staff. To my surprise, the little hints and comments Norman made on fairway mowing lines, fringe grass maintenence and the presentation of hazards were very insightful, and were subsequently followed to the letter, much to the benefit of the course. These words have slowly faded from memory for some on the ground crew, to the detriment of the course. A further visit and like instruction would be very positive IMHO.
