Guys,
Other than maybe the addition of a tee or two, there will be no real differences between the setup for the 1995 and the 2004 Open.
If there had not been hard rain on the Tuesday prior to the 1995 Open, 5 over probably would have easily. I know it's difficult for people to realize that sometimes, but it never fails that if you need rain at your course, schedule a major championship.
There is plenty of room to lengthen many of the holes at Shinnecock, I am sure #7 will not be one of them, there may be a new tee placed to the left of the current one...apparantly where the tee was originally placed by Raynor. The 5th tee may be bumped back a bit as it usually plays downwind....but it's still pretty tough, just ask Tom Kite who chipped it back and forth across that green.
It's amazing when you think about standing on the back of #18 tee with a guy who has made the cut in several U. S. Opens and thinking about how far that tee can be pushed back. Then we both proceed to play the hole with a good drive and a wood.
