Perhaps Kohler is feeling the heat from Erin Hills and the pending Sand Valley.
I live in Chicago and went to the American Club (Riverbend, actually) with my wife last summer.
It was the 3rd weekend in July - prime time in WI - and the MV and River course were WIDE open.
No, I'm not talking a few openings here. I'm talking EMPTY at 1:30 pm with the parking lot 1/3 full. We teed off at 2 and did not see another group on the course.
Did not go to Irish or Straits.
But, the Straits, at close to $500 all-in with a caddie, is not a course I intend to play more than once every 2 or 3 years.
The 5th course is going to have to be something special to distinguish itself. Dont know if Pete Dye will do it. Has anyone heard.
