Wayne and Mike beat me to it - #1 is a world-class opener - great tee location, great flow to the fairway, great bunker placement, and a green that'll make your knees shake if your ball is in the wrong spot.
#17 - wow. The first time I saw #17 was unforgettable. It was during the US Amateur and I'd just walked away from the famous 16th with the match. I got to 17 tee and thought, "this is a crescendo". Playing back over the quarry to a great green complex, it plays with your nerves and your soul.
The whole darn place is so special. Don't tell anybody, but I've actually driven up to Ardmore just to drive around the place.
