OK Pat, back to this one.
I played Pine Valley yesterday and as you can imagine I was very interested in the specific details you and I (as well as Mike Cirba but he ducked out awful quick
) spent a few days discussing based on our memories. I'll try to address as much of it as possible here.
#17 has two sets of (one or two) trees that could be considered impediments to approach shots from the fairway. The first set is just about at the end of the fairway, maybe 70 yards from the green. The second set is the one you referrenced throughout this thread, it is immediately adjacent to the green on the left. The trees at the end of the fairway are relatively small by comparison to the one(s) next to the green, they're actually a different type of tree. The tee does not in any way align the player to the left side, if anything it aligns you up the right center. I would call it the center, but at the very beginning of the fairway (about 140 from the tee) its actually the right side of it. The cant of the fairway you referrenced as steering balls to that left side is only in the right half or two thirds of the fairway, the left one third to half is sloped to the right so as to steer balls back down to the center. I'm really not sure how you can position your argument with the following two points; the fairway slopes to the left which forces otherwise good shots over behind the trees, and at the same time say "most players slice the ball especially with it below their feet as it is when you're behind those trees". That's not really my point here.
My point is to let you know that the only time either of those sets of trees impedes upon a players shot when he is in the fairway is when he is in the furthest left 5-7 yards of the fairway for the last 30 - 40 yards of the fairway, and aiming for the left 1/4 of the green. In other words, if you hit the 200 yards off the tee and are 1 foot from the left rough you will have no tree issues all the way up to the left edge of the green. At 220-260 from the tee and in the left one foot of fairway you will have a two sets of trees in your way to that left 1/4 of the green, the first set is not really an issue unless you have driven way up to the end of the fairway because of their height, most any player can hit it over those trees, especially from the uphill lie given. The greenside trees could very well block a shot coming down on that line (to the left 1/4 of the green).
You will see the next time you're there that while these trees may not have been on Crump's planting list (none of us know for sure due to the circumstances of his death), but they certainly do not overly impede on the golf course. The one thing I really noticed was the lack of incentive for a player with the ability to carry the ball 215 yards or so to actually take on the bunkers on the right for the benefit of a more level approach to the green. There is a really nice looking perch in that right side of the fairway that would be a great spot to play from if the risks of being in the short or long bunker or the trees on the right were more in balance with the rewards. Then again, maybe they are when the greens have a little bounce and some speed, those left corner pins are very difficult to look at from the middle/bottom of the fairway and would be much more accessible from the right perch. Anyway, pay close attention the next time you're there, I think you memory will change a bit.
Now, to give credit where due, on #12 we played the right hand tee and I really wanted to take a shot at the green. I cannot very well hit a running hook so my only approach was going to be a high drive at the front corner of the green, but the fact that I could not see anything left too much uncertainty and I hit a 3 wood out to the right and pitched on. Now remember, that's from the forward right tee, and the left tee is the primary championship tee, and the guys told me they rebuilt the left hand tee this year so as to make it the primary tee for regular play as well. From the left tee you cannot see the green very well even if the trees are removed all the way to the crest of the ridge line (which is only a couple of yards outside of the left edge of the bunkers). Removing those trees would certainly be a visual enhancement (plus the fact that there are about 8 bunkers all through there), but you would not gain the strategic visual effect of being able to see the green.
