Proliferation of trees is still a terrible idea for the average golfer.
Maybe we ought to start another thread rather than 'jacking this one but I think this is a good jumping-off point for an important discussion...
I think when majors roll around it reveals a fundamental, usually hidden conflict in the minds of most participants in this forum. Namely, it's that what's great for any of us or what's great for the average golfer is seldom the same as what's great in a competition venue for the best golfers in the world.
If we were going to hold a GCA event and could choose between Augusta National c. 1960 and Augusta National today I believe the majority choice would be the older version. Heck, make ANGC c. 1940 an option and it would maybe be unanimous. Yet does anyone really think that the course as played in the 60's would offer as interesting and varied a challenge to Tiger Woods and Zach Johnson as does the course they played last week?
For anyone that posts here (perhaps excepting Obee, JES and a few others), having to hit a recovery shot from a terrible angle onto a hard green is plenty of challenge after an offline tee shot. Heck, having to hit shots from the middle of the fairway to some of those greens would be a killer for most of us. Even pretty good players can enjoy and contend with TOC-style "strategy" given the caliber of greens available at Augusta National.
But take Tiger as an example. At TOC on a calm day or at a treeless, roughless version of ANGC on almost any day he can hit ridiculously wild driver shots and get off scot-free as often as not. The only way to keep the Masters from turning into Bomb and Gouge (without the Gouge) under those conditions would be to firm up the greens and tuck the pins to such an extent that they are practically unplayable from the middle of the fairway. That's hardly golf.
Sufficient length and power, in the absence of penalties for wildness, render any reasonably playable course able to be overcome through brute strength. Once in a while that may make for an interesting tournament but it's not traditionally what we look for in a major championship venue.
My point is that the very features that can add interest for 99.9% of golfers (strategic width and angles, options for recovery, etc.) tend to subtract interest for the strongest players. And vice versa. All those trees and the "second cut" at ANGC surely render it a somewhat less intriguing and fun course for a 5-handicap member or guest. It's a balancing act required by the mismatch between what most golfers need and what is required nowadays to identify the best player in the world (for that week).
I think it is possible to walk a fine line and serve both purposes with one course. There are a few links courses that can do it, at least under the right weather conditions. But this disconnect is at the heart of much seemingly inconsistent back-and-forth in discussions on this forum
