How is Madison not on this list? I'm not much of a fan of the Badgers but that is a fantastic town with a ton of success over the past 20 years and a rabid fan base that consumes the whole state, which is obsessed with Beer, brats, and cheese. This is a no brainer as a top 25 tailgate.
Side note: all i ever hear from Iowa fans is how much of a pain IC is to get in and out of and how that has such a negative impact on their gameday experience. It's rare for me to hear an Iowa fan say ISU doesnt have the better tailgate. I've heard a ton about "Kinnik is a great atmosphere" but a rarely hear anything about Iowa's "Tailgate".
