this is obviously just one person's experiences, but my father attended various Badgers road games: Purdue, Illinois, Minnesota, IU, and I believe Northwestern, and also Iowa. Great experiences with all the opposing fans except at Iowa City. Not just a bad experience, but an atrocious experience with Iowa fans. As in never did and never would go back. Conversely, both from experience and from various internet posts, Huskers fans were entirely civil.
