I think Raynor or Banks worked here. Many courses in twin cities area have splendid rolling land, are the terrain and the greens at this Blooomington course worthy of study ? Any restoration going on.
I have seen this credited to Seth Raynor. I e-mailed George Bahto a few years back and he told me there was a field employee of Raynor's that was probably on-site and did most of the work. Having a sense of humor he put the Biarritz green on a par 4 and not the natural choice of the very long par 3.
"Worthy of study"? Well, I think there is a reason you haven't heard much of this course. It is good. Not great. Raynor's best in the area is Somerset, which is superb.
I could cite holes for you at Minnesota Valley but they've changed the sequencing a lot. I don't know which holes are which now. I used to play there in the late 80s and early 90s - before it was so important to know who designed what. Frankly, I was surprised to learn that Raynor is credited. Then I remembered the 7th green (friend used to joke that the course got its name from the swale) and very long par 3 11th.
Minnesota Valley is a rung down from better area courses like Golden Valley, White Bear, Minikahda, or Somerset. I'll even say I think Eau Claire is a better course. Study that one if you are in the area.
