The are a number of areas of the course where the trees have thinned out over the years. The locations that stand out in my mind are 11, 12 tee, and 17, though I don't have any direct knowledge of removals they've done. A few removals would go a long way at MV. 5, 8, 9, and 15 could stand to be peeled back a bit farther away from the fairways/greens. If memory serves, those trees in the middle of the fairway bunker complex on 18 are ash trees. Outside of Jack I don't think anyone will cry over the loss of those trees to the ash borer.
