I can only comment on La Crosse and Madison. I'm a La Crosse grad and went to the Madison for a few football games.
The La Crosse is all one space, it's not spread out all over the city, there's lots of nice green spaces, benches, trees, etc... and it's always very well maintained and just a great environment. I was a commuter student and after my freshmen year, I didn't pay for parking again, I'd park on one of the city blocks around campus and walk in, always a pleasant experience. The pics on the Wiki page for La Crosse are representitive of the campus. Lots of nature trails, the marsh and hixon forest for hiking and it's in a nice quiet laid back part of La Crosse.
The campus also has pretty nice education buildings and dorms, the food is decent, it's all in all a great place to go to school.
Heh, my freshman year (1996), in state Tuition was $1350 a semester! Now it's closer to 3k I believe. Still a good deal compared to many other schools but it has gone up.
La Crosse is known for their Health/Gym/Teaching strengths, but it also has a really strong business school, and a pretty good comp-sci program as well.
As for Madison, their academic credentials stand on their own, the one thing that struck me was that the campus is kind of all spread out over Madison. You could be in trouble if you have back to back classes in different buildings.
