Terry and Richard,
Telling holes apart on television is difficult for the average viewer who is basically unfamiliar with the course, and in some cases, even for those who are familiar with it. That's because the viewing angle and perspective is very different from what your brain memory tell's you it should be. And this is with or without trees.
For example, and bethpage is a good one with this, most people couldn't tell you whether a player was hitting the ball from the left rough by the bunkers on 10 or 11 when the view is from the side as they both look the same and there are no trees in view.
Imagine, also, what may have beens een on television if they hadn't removed the more than 10,000 trees (that number is correct) prior to 2002 and another 1,000 before 2009... for whatever that may be worth in the discussion.
