I'm sure that additional tree removal would help in certain locations, but, as I examined the holes two things, or actually one thing stood out, but, on three holes.
If the trees behind # 17 were removed, it would be a sensational "skyline" green, which I believe it was when it was first crafted.
Ditto # 2.
I think the same thing about # 9's left side green.
I know that idiot-savant, TEPaul. claims that the trees behind the left side 9th green are necessary for bank stabilization, but, I don't accept that those particular trees are the only method of bank stabilization.
And, some of those trees are on top of the bank.
Someone posted an early photo of the 9th green showing it as a 'skyline" green.
If they could repost it on this thread it would help.
# 9 requires a far longer approach shot than # 17, which is basically a wedge or short iron, so the fear factor isn't as high as the shorter distance and club used for the approach somewhat ameliorates the fear.
But, on # 9, the fear factor would be incredibly high for two reasons.
1. the longer shot is more difficult to control and makes a back hole location ferocious.
2. Everyone knows the consequence of going long and it's frightening.
# 2 lies somewhere between # 9 and # 17 regarding the fear factor.
This one act, restoring the "skyline" feature on those three holes, would improve the play of the golf course without any substantive intrusion on the play of the golf course.
