The Road Hole provided something of an "Oh wow" moment when I first rounded the corner of the hotel/OB.
It's not exactly the most intimidating approach shot, but the second shot to #13 at Caledonia is pretty neat in that way. Sharp dogleg-left, shorter par 4 where you pass a big oak on the left and into view heaves a green almost completely surrounded by a big waste bunker.
The first glimpse of the opening green at Pinehurst No. 2, knowing that the next 17 are going to be that shape and similarly difficult to hit. Ditto the first glimpse of the first green at Yale.
