The Old Course is as close as ideal for everybody, so is Royal Melbourne in my mind... the thing is, as long as people don't know how to PLAY golf, all the courses are wrong,
tee should be inclined to help slicers, not enough width here, too slopy there, greens should hold more, bunkers are too severe, grass is too long, bushes are trouble, to many holes into crosswind, cross bunkers is too hard a carry (but a river is fine!!!!) no mounds to prevent ball from going too far off line...
This way maybe Oakmont is perfect, it's tremendously hard for everybody.
