Pros:
This course has great tee boxes, great chains, a pretty good variation in altitude for where it is, and spectacular views of the Flatirons. Happy people abound and will always at least say "hi," if not more. It's located right in South Boulder, a 10 minute drive max from anywhere in town.
Other Thoughts:
The city has made great use of this patch of grass. The fact that they could squeeze this course into South Boulder outweighs the fact that there are only 9 holes. I don't think a course should be judged by the number of holes it has, but rather by the quality of holes it does have. This course is a fantastic place to spend Sunday afternoon with some friends and some beers. I have played this course at least 20 times, and have never had a bad experience. In fact, I've had nothing but a blast everytime I've played here!
