How does one label a golf course? Links courses are easy to identify, but how do you describe Pebble Beach? Parkland and Heathland courses are straightforward to identify and label, but is there a category for Sand Hills (other than "Excellent")? What about Erin Hills, near Milwaukee? Is there a label for courses routed over the kettle moraine areas left by glaciers? How do you describe the type of golf presented at Erin Hills, laid out over such terrain with a mix of traditional and innovative ideas and designed with the intent of hosting a major championship? While the driving game is primarily one of the ground, the approach shots present the more modern challenge of aerial golf. As the greens are bent grass, they will hold a well-struck approach shot, and, as so many are elevated, bouncing the approach shot into the green is rarely the best play.
