Let's see:
New York--Bethpage Black...OK...
Colorado--City Park GC!
This is just stupid. City Park isn't even the best muny in Denver (Wellshire is). There are 4-5 munys in Aurora that are much better. What about Fossil Trace, owned by the City of Golden? How could anyone publish something like this?
I have a great fondness for City Park GC, but it's hard to know how you would define your ranking system in such a way as to present it as the best muni in Colorado. I can't say it's marketing or any of the other theories previously presented here. It sure does get a lot of play, though, so that must be it.
On the plus side, it's very old fashioned, it's right in town rather than out in the sticks, it's cheap, and there used to be a quality bbq place right there in the clubhouse. On the negative side, though, the good bbq has been replaced by mediocre mexican food, the course is hopelessly old fashioned, and it's right there in town so you might hit someone's car off the tee and get your ass beat by the car's owner (don't laugh, it's happened). Seriously, though, Doug's right. It's got its charms, but I can't rate it the best Denver muni (I like Wellshire, Willis Case, AND Evergreen better), much less the best one in the state. For me, I'd probably go with Murphy Creek out in Aurora, but I can't say I've played all of 'em.
