Wisconsin native Andy North has built two somewhat high-profile courses in Wisconsin -- Trappers Turn in the Wisconsin Dells resort area, and Bergamont in suburban Madison. TT is a pretty good course; Bergamont is not. It's idle speculation on my part, but North had a nice piece of land to work with in the Dells, and turned TT into a challenging but not overly demanding course that's full of variety. Bergamont was done as part of a very (for Madison) upscale housing development -- some of the homes lining the course are among the largest and most expensive in the area. I don't know that the housing needs of the development co-opted the best land, or that the land simply wasn't as conducive to a good course. And maybe he had less $$ to work with than he did up in the Dells. Bergamont has a several decent holes, and even one or two excellent ones (the par 3 17th is quite good, I think). But overall it's clearly a notch or two (or three) below TT. Bergamont recently went private, after opening a few years ago as an upscale daily fee course. TT remains (from what I can tell) a pretty popular daily fee course, relying on the summer tourism season at the Dells and priced well below the high-end Kohler courses in Wisconsin.
In conclusion, I'd call Bergamont a mediocre course, and TT a pretty-to-very good one. Bergamont was built as part of a housing development, while TT was not. Maybe that's not the defining reason for the difference in quality, but I suspect it played a role.
