John Kirk is right. It was the 17th, when Tiger stopped at the top of the swing. It seemed to me that the tee was a good 20 yards away from the green. The thing that was claustrophobic (wheres the spell checker when you need it) was the grandstand behind the 16th green, and to the left of the 17th tee.
That said, congratulations to the USGA for keeping the public back in the tree line and away from the rough. Its been good for us TV viewers, hope its been OK for the fans that turn up. There has been a definite reduction in the numer of shots played from trodden-down rough this year. I'm similarly looking forward to the Open at St Andrews, when the fans are out-of-bounds, aren't they?
