I've only played one P.B. Dye course, Atlanta National, during U.S. Mid-Amateur qualifying. Let's just say that it didn't make a favorable impression on me.
The two others in my threesome were club members there (or at least one of them was). Incidentally, BOTH qualified for the Mid-Am that afternoon--each in a playoff.
There was a par 4 (the 16th?) that may have been entirely blind! I say "may have been" because I wasn't playing particularly well and may have selected the wrong line of play.
I recall thinking afterwards: "Boy, I guess I should have played a practice round here before trying to qualify...or maybe not."
They have an excellent head golf professional there, however: Clark Spratlin.
