That likely has something to do with it, but not much. Trees play a significant role on 1, 4, 5, 6, 14, 17. So it's not like the course is treeless.
I think what gets people are the trees directly in the way off the tee. Look at the aerials posted in the other threads... you have to hit right over some trees to reach the fairway.
And that is weird. Then you combine this with the very tight nature of the hole up near the green, and there's the dislike.
None of it bothers me though. Oh, like I said earlier in this thread, I can't call it a great hole... but I also don't see it as an anticlimax.
