If the mountain courses are closed, you might get someone to meet you at Colorado Highlands University course, or if you can manage driving 25 minutes south of Denver, to my home course, Jellystone at Larkspur; a very unique terrain course ($5 to play, no crowds). Plenty of folks would be glad to show you around there. Down in Colorado Springs, see if you can get on the course at Sakuna Pines in Black Forest, a brutal private course run by a Christian camp that doesn't allow any trees to be cut, but it's icy if there has been snow. Best of luck, and here's hoping for sunny and 55!
