With so little experience at playing great courses [none, actually], I must go by what I have seen somewhere. Of PGA courses, surely no one can watch 'The Masters' and not want to play AN [especially #12].
And any 600 yrs old course would be incredible ..... oh, yeah, only one of those.
I lived in TN a while, and heard constantly of an amazing and snotty private; so The Honors course.
Online I have seen a few 'wish list' courses. When searching golfcourse.com for something in S IN to play, found Victoria National. Took me an hour to realize it was private, and my plans were moot. [But, who knows
].
GCA got me interested in a 'supercourse' on a truly ugly piece of terrain. Sand Hills might be OK. *snicker*
Obviously many others, but I think John meant the REALLY wish list, not just everything you could think of.
But YOU should want to play more 'mountain golf'.
