My wife and I recently took a vacation to North Dakota and played the Links of North Dakota, Hawktree and Bully Pulpit. I was impressed by all three courses.
Hawktree was the first course by Jim Engh that I've played and my expectations were met and exceeded. The amount of earthwork that was no doubt required to fashion the course from the "semi-canyon" was relatively well hidden.
Bully Pulpit was absolutely fantastic, with holes 1-13, 17 & 18 being what I would consider (perhaps naively) wonderfully minimalist. Those holes are put in stark contrast by 14, 15 and 16. Hole 15, which I am sure has been discussed here before, was the greatest golf hole I've ever seen or played.
The Links of North Dakota was another story. I feel a little like the jock in many a teen movie that can't see how beautiful the nerdy girl is just because she's has on a pair of glasses. Though I could see the wonderful architecture, it was quite obscured by the horrible condition of the course. Several greens and most of the tee boxes were less than half grassed. Large portions of many fairways were barren or full of crabgrass. I can only imagine that upper North Dakota has suffered through a terrible dry spell. They had extensively slit-seeded, so the condition may improve. We were originally scheduled to play 36 holes one day but left after 18, quite disappointed. I would still consider myself a fan of the course, and recommend it to others, but I couldn't force myself to play another round that day (it also happened to be the last day of our trip, which may have also been a factor).
