The new course that you are asking about is called Erin Hills and is located 30-40 miles northwest of Milwaukee in the town of Erin Hills. It is a spectacular, natural site. In fact most of the golf holes will require little or no earthwork at all. Many of the greens will be natural core-outs and may be constructed with on-site sand. Construction has started and this course will be seeding in 2005. The bunkering will be great part of this golf course.
I first saw this site about 4 years ago after meeting Bob Lang the owner of the site. He has a passion to build (discover) one of the great golf courses in America, and has the potential to do this with this site. I have toured the site with Dana Fry, Mike Hurdzan and Ron Whitten on numerous occasions, and they have spent countless hours finding and tweaking this course. This is one of those courses you will have to play. The fairways of the course have been carved out by mowing the native vegetation and if you look at the photos of this site, it looks as if it is ready to play and as of yet, virtually no dirt has been moved. You do not need to worry about this course being maintained to the fullest as they all want it to look natural, even dry around the edges. The native grasses and fescues are spectacular already and very little will need to be disturbed except for the actual fairway areas which will most likely be a fine fescue blend.
Dana, Mike and Ron also have a great passion for this site and I truly believe that Erin Hills has the potential to become one of the great golf courses, and a course that GCA guys will truly enjoy.
I also concur with your statement about Shelter Harbor and Hamilton Farms. The bunker work at both of those courses is spectacular. Also, you have not been around if you have not seen a great Hurdzan-Fry golf course. They have designed some great ones in the past 6-10 years, and the two above are only a sample of what they can do. Erin Hills, their latest will be a course that will be talked about for many years to come.
