Mike,
I'll try to follow you, but it won't be easy.
What slope of the hill kicks balls away on 13? The slope up to the green? That just stops balls. The slope on the right above the green? If it weren't rough, it would kick balls onto the green. By the way, I'd take that bunker out completely as it was wrongly put in. If kept, it would be better as Flynn had it, lower in the hill and turned 180*. But as it is, I think it would be better out altogether. The slope on the right of the green? That does deflect balls away from the green but the green is missed regardless and that is a good thing and obviously in the architect's mind when he conceived the green site.
In any case, the proposed bunker is not a greenside bunker but is a fairway bunker well short of the green. You are not comparing like holes at all.
I don't think there is any way you can determine what Flynn was thinking. You can make empirical observations about Flynn's designs but that's about all. If you cannot grasp that Flynn was prone to making changes at his courses (OK, he didn't make one here) and that he would consider a broad range of factors 80 years later in a more open mind than you do, I think you are mistaken.
What is obscure about the slope to the right of the green on 7 that some people wouldn't understand? How is there no way to control the ball and where is all the randomness? It is in rough right now and needs to be returned to fairway height as I mentioned many posts ago. The crapshoot you speak of is not something I think of after studying the grounds on that side of the hole.
A bunker would lessen the mental test? Preposterous. Nobody mentioned that the bunker was meant for a mishit drive. It was discussed what the ramifications are with a mishit drive, as well as other scenarios. Holes don't play one way because our results differ from day to day. We aren't Hogan landing the ball within a few feet of prior shots all the time. Our own randomness is a factor and this needs to be expressed in hole designs.
I don't miss the left greenside bunker in an analysis. What gives you that idea? It is obvious I understand the design features a lot better than you do based upon your posts and previous discussions. The point in Flynn placing the green where he did (you wanted to move it 50 yards down and 30 yards to the right) is to utilize the ground contours. The area is not flat, the green slopes right to left. Times have changed and a bunker is better today than it would have been 80 years ago. That shouldn't be too hard to consider. I think the greenside bunker should be pinched in a little more than it is and reconfigured as it was originally designed and built. It is a poor derivation of its former self as is the case with too many bunkers at RGGC. It is a major flaw at this time.
If you like that last hardwood tree, why would you want to see the fairway returned around the right side of the green? I think it is less onerous than the evergreens because it is even with the green and not in front and it is not an evergreen. But it is still a dumb tree. You like it and it isn't Flynn. What's that all about? You can't have it both ways when you use original Flynn as a be all and end all standard.
"BTW the eminently qualified architect wanted to keep the last evergreen ; I suggested to him that "Flynn was rolling over in his grave" and he changed his mind."
Are you sure about that? In any case, just because you had one good idea (even if it is evident) doesn't mean you're on a roll and have other good ideas
Please don't tell me about Ran's opinion of RGGC when he and I played it. You want to make more significant changes to the course (moving 2 fairways) so don't act like you are some steward of William Flynn's design. The course has a long way to go to become close to his original design. While the greens are very close, except that atrocious 16th, there is a lot that needs to be done in terms of trees and bunkers. A fixed point in time as it relates to a design isn't necessarily ideal, especially when considered 80 years later. Come on, that is utter nonsense. And to say building a new bunker would open Pandora's Box? That too is crap. You want to make more significant changes and accept ones already made. Pandora's Box is opened when committees decide things without a complete understanding and when they compromise architects' suggestions.
I go out in the field and discuss work with architects a fair amount. I think members add a lot to the discussions because of their greater familiarity and play experience. But the wrong advice can be given as well. The consulting architects should listen, but as Flynn suggested, after a while, they have to be left on their own to utilize their expertise and experience.
Remember, a bunker is not permanent architecture. A golf course isn't a monument either and you shouldn't continuously think of it as one, except when you don't as it relates to your own ideas
