Matt,
I'll chime in with a couple of thoughts.
First, to preempt the ineveitable BillV/Redanman comment, we are at 5,000 feet altitude and higher, so there's a question according to some whether we really play "golf" here...
Second, we are blessed with an abundant quantity and quite good quality of courses in the Denver metro area (Riverdale Dunes, Murphy Creek, Fossil Trace, Buffalo Run, The Ridge at Castle Pines North, Bear Dance to name a few), and in other areas such as Pueblo (Walking Stick), Colorado Springs (Antler Creek), Fort Collins (Art Schaupeter's new Windsor Highlands along with a couple others) and out west in Grand Junction (Devil's Thumb and Redlands Mesa).
One of the good things about the development of golf in this region has been the active participation by and partnership between the municipalities surrounding Denver and private developers, which have put public courses in with large housing developments that have been carefully thought out, don't have intrusive housing (for the most part) and have hired quality architects to do the courses. Many of those mentioned above fall in this category. The fact that a number of different architects have worked here (Foster, Kavanaugh, Pete Dye, Nicklaus, Weiskopf, Morrish as well as local products Engh and Rick Phelps) has contributed to the variety and the quality.
Third, it is generally a decent value proposition here as well, with $30-$40 being the price point for most of the new courses. Some like Vista Ridge and The Ridge at Castle Pines unfortunately are CCFADs run by Troon Golf running to $100 a pop, but they're the exception to the rule. The lackluster economy and the influx of new supply has kept price inflation to a minimum over the past few years. I haven't seen much discounting, though, and courses like Bear Dance and Fossil Trace always seem busy.
Fourth, I don't think the public mountain golf in Colorado is at a par with what is on the flatlands and foothills of Colorado. Most of the quality new mountain golf is private (Red Sky Ranch, a couple courses in Aspen) not public.
So yes Matt we are quite fortunate to have what we have here. So much so that there are a number of courses here that I have yet to see, or have only seen once. I need your job!
