How about what courses you think should be in Golf Digest's top 100 and aren't.
Forget Golf Digest's critera for this exercise.
Here's the new criteria: a top 100 course just says hello to you, and by the time you're done, you know without a shadow of a doubt that you've played one.
I'll start with:
Lakota Canyon near Aspen. I've posted a lengthy review on this course before, but suffice it to say, it's like a roller coaster ride, on thrill after another.
The setting is spectular in the foothills of the mountains. Not in the flat looking at the foothills as so many courses are, but literally in the foothills and the holes wind around the natural contors that water, wind, graivity have produced over 1000's of years.
