I've been to a ton as well. I've been to Iowa City for it. It's not the same. We have plenty total morons too but the ratio is definitely not 1:1. There is an utter beligerence to them that is unmatched.
And that's also confirmed outside of our ISU bias. Talk to fans of other B1G teams and they'll all mention Iowa fans as the worst or among the worst in the conference/college sports writ large.
My brother might've been a bit skeptical of my Iowa fan ******** and then he got jumped in Indy during the Mich/Iowa B1G Champ football game.
Going to a bathroom in a hotel/restaurant, 2 Iowa fans saw his Mich garb and jumped him, trying to kick him in the face while he was on the ground. These were young guys and he's a middle aged man. Now he hates them as much as I do. Lucky for him he wasn't seriously hurt. Iowa fans are the absolute worst, they really are.
