Here's a nice story on Erin Hills and its hopes of landing a U.S. Open. Well, the story seemed well-informed until reaching this point:
Designers Dana Fry, Michael Hurdzan and Ron Whitten have done some brilliant bunkering around the greens and fairways. Lang and general manager Steve Trattner also had some input into the overall course design.
Rather interestingly, while the dropoffs, undulations, rough and wetlands come into play on just about every hole, very little earth was moved on the course. On 14 of the 18 holes, not a single shovel of dirt has been turned.
The course has no signature hole. All of the holes qualify for that distinction in their own ways.
