A new flock is taking over Ptarmigan Country Club. The club outside Fort Collins was purchased this month by Heritage Golf Group, a Virginia-based operator that expanded into Colorado two years ago. Records show the company paid $6.1 million for the land. Heritage now owns 39 private or semi-private courses across the country, including The Golf Club at Bear Dance in Larkspur, Plum Creek Golf Club in Castle Rock and Colorado National Golf Club in Erie.
