That's easy
Grand Junction. I'd say it's one of the best places to live in the country, not just Colorado. I don't know much about waterskiing opportunities around here, though I do have lots of friends who do it (1 is selling his house on a private waterskiing lake if you're interested).
It's a perfect size community (about 130,000) with outdoor recreation opportunities that would be hard to compete with anywhere.
