I see many high end clubs doing the same thing in the name of "fairness" - one club I know spends $100K annually on tree trimming of this sort. Presumably, it has to go down sooner or later. However, if a member can ask why he shouldn't have the same shot out of the bunker as he has from the fw, why not ask if he should have the same shot out of the trees as he has from the fw?
As to Bob O Link, the same neighbor who belonged to Medinah and introduced me to golf (No. 3 was my first play) also joined BOL as a second club, so I got to play there a fair bit. It was there that I first lost a "Double Secret Chicago Press" bet, of course, not even knowing what it was, since it was, well....secret, until they announced it!
Pretty flat on the front nine, especially, but good holes nonetheless. One of the few with the first hole also being no. 1 handicap hole. It didn't seem particularly over treed 25 years ago, but a lot can happen in that time frame.
