Pat- Here are two examples of why I think the afore walk is NOT beneficial.
I recently toured a course and as I was seeing it, it occurred to me that when I saw the sign that said "resort" is what I call the writting on the wall. I don't feel the need to ever golf there, because it would likely never make the top 100 list even if half the country fell into the ocean.
The other i.e. is when I was going to Caddie in a tournament at a course I had never seen. The notion that I wasn't allowed to golf, while I went out to learn the greens, was preposterious, to me. (It was all about the arrogance of the image they wanted to project)
Well, I learned the greens and caddied three rounds there. Little to no strategy considerations other than middle or right middle or left middle. I still have yet to golf that course and I would not presume to give it a rating. Why, because I did not golf it. I have no idea how the course plays, but I do know the features that are there. All I really have is a pre-conceived notion. When I show-up somewhere I have never seen, and I golf, first, I have no notion what lies ahead. Allowing the architect to take me on a tour of his interpretation of the topography.
