The designer of the golf course knows something you do not.

He knows how far the golfer is trying to hit the ball and just at that location he will place a bunker or a water hazard. He will make the fairway a bit narrower or make a dogleg. If the golf course is too easy the fun is gone after a while. It shall continue to be a challenging game for a long time.

Looking towards the green from the tee off you have an idea on what the golf course is like. When you reach the green and turn around, you may change your mind ? and the next time you play you are better prepared.
