I haven't played enough top 100 courses to have much of a list, but right now, Royal Dornoch would be on mine. I have to admit that I was played like poop the one time I was there, but even if I were playing better I suspect the length of it was just too much for me to want to play it all the time.
I think we played the medal tees when we were there, so I would love to go back, and play it from the gents tees, to see if it really was all about the length.
I do know this, I wouldn't want to play a "hard" golf course every day, especially if it featured a lot of places where a marginal shot results in penalty strokes or a lost golf ball.
Yesterday I played Angel Fire Country Club and I don't care if I never play there again. It's a classic example of my least favorite kind of course. It would be relatively easy for a low-handicapper, and almost impossible for a 20.
Tomorrow, it's Black Mesa, and I am looking forward to my second trip there with relish.
