Gentlemen,
Here are some photos of Medinah I took last May. The one thing I noticed was that Rees Jones has "rees-ified" the bunkers with more definition to them. Many trees were cleared as well since 1999.
The 1st Hole with the new tee. If you remember back in 1999, the back tee was right before the cart path you see in front and had a flower bed around it. In 1999, it played at 388 yards. Now it plays at 438 yards.
The approach to the 1st hole. They cleared out a lot of trees behind the green and now there is a view of Lake Kadijah from the fairway. Jones also added a collection area in the back of the green when it used to be deep rough.
The 5th hole, par-5. Should be the easiest the pros face.
The 7th hole. Tiger Woods in 1999 reached this green in two with a slicing 2-iron.
The 12th hole. One of the more majestic holes at Medinah, and it feels like a racecar speedway with the heavy slope from left to right.
The tee shot on the 14th. The pushed the tees back to make it a 600+ par-5, and it should be interesting.
The 16th hole. This was one of the most awkward dog-legs I have ever played in my life. I think the turn is way too sharp and it almost forces a player to have to hit iron of the tee just to keep it in the fairway.
The 18th tee. A neat little tee shot that requires precision.
The re-done 18th green. Jones raised the green significantly and added a collection area in the back. The green is much smaller than it was in 1999.
