Not in their plans or imagination? To whom have you spoken?
The idea for restoration has been there for three or four years now, and the current superintendent (Craig Moore) has the original Langford plans and has been removing trees one-by-one since he arrived on site a little over a year ago. The plan is to do the little stuff like that over a period of time (and tackle bunkers at the same time), and eventually take on the much bigger project of restoring green sizes (tricky with the current irrigation system - sprinklerheads on the fringe now would end up inside the original green sizes).
The original Langford plans were for an entire 18-hole course, part of which is currently occupied by an adjacent neighborhood. This means that a full restoration (including a complete re-do of the Gill holes) will call for additional interpretation of Langford's intents and some compromises since they can't completely put his original plans into the dirt.
But the plan is there, and your dopey conifer comment in the Golfweek review was a great description of a problem that needs to be dealt with, and I think did a good job of alerting several members to that fact.
By the way, people making the trek to Greywalls who are also interested in the Langford holes should make a point of stopping by Iron River Country Club in Iron River, also in the UP (just across the border from Wisconsin). They don't realize what they have, but it's another Langford 9-hole layout that has added less trees than most and retained much more of the original features. I highly recommend it, and of course it's dirt cheap.
Edit: By the way, I can post several photos of the Langford holes at Marquette later on. The push-up Langford greens are boldly contoured and are easily identifiable to anyone playing the course trying to differentiate between those and the Gill greens.
One thing which surprised me was that Langford had a 240-yard par three which has since become a 240-yard par four from the white tees and a 280-yard par four from the blues. This is due in part to the shrinking of the green, but in an age where short par fours and fives are becoming par threes and fours, can anyone else think of a classic era hole which has not added much length (if any) but added a stroke to par?
