Doubt it. Like I said the only other fan bases that I have ever heard say this are Iowa and ISU, wonder why? lol. Even Texass fans say that they were treated well in Lincoln, so chances are if people were obnoxious to you, it was because you brought it on yourself. Been there multiple times, and I've never seen an opposing fan get treated rudely. Maybe some friendly ribbing, but nothing bad. We check our own, if we were to see this, we wouldn't go all Big 10 on someone.
Funny thing, I've heard that pretty much all Big 10 school are very inhospitable to rival fans, PSU, Ohio St, and Iowa being the worst.
