To me , Flynn's genius is setting up recovery shots to well designed green complexes. Trees PLANTED along the sides of fairways ruins this wonderful design concept.
Mike-While I agree with you that it likely would have been better without the added trees, I can see the practical reason for doing it. They were added between holes 1 and 6, 3 and 5, 5 and 6 and a few along the road on 9, 15 and 18. In all cases, it would seem those trees were added for safety. It is fairly easy to hit into the adjacent fairways on those holes; some guys hit from the 1st tee into the 6th fairway as I was playing along, I played with a guy who near shanked one into the 5th fairway from the 6th tee and I hit some shots from the 5th tee that might have ended up in the 3rd fairway if not for the trees. So, architecturally they might not be the best, they are better from a safety perspective.
