The beautiful Walter and Mahala Douglas mansion, called Walden, is on Lake Minnetonka (just west of Minneapolis) and worthy of a visit. Someone posted a picture of it here once.
John and Nelle Pillsbury Snyder lived in a mansion in Wayzata, a wealthy town which is on the same lake. I wish I could be more specific.
About 100 miles SW of Minneapolis, there is the small town of Madelia, which was the birthplace of 'mystery man' gambler George Brereton/Brayton. I've never been there, but it's easy to find on a good map.
I'll let you know if I find out anything else. : )
