I've only played it once, but I'd put in a shout out to Keller Golf Course, Ramsey County, St. Paul, MN.
The course is closing for a two year renovation. We had a thread on the topic not long ago. Richard Mandell is the reno archie. The course was a solid test of golf when I played it, with very cool use of terrain and routing scheme. It has tremendous provenance with a rich historical tournament history for both PGA and LPGA events. I sure hope Richard Mandell hits a homerun with his work there.
