Hey guys, Wisconsin fan here and I come in peace with information. In addition to this being a night game at Camp Randall - which is normally a recipe for a bunch of "well-served" patrons - it is also the Madison Halloween celebration night known as Freakfest, held on State St (which is an 8 block stretch between the capitol and campus). It is a lot more "corporate" than it used to be, but it attracts people from all over. It will be crowded in Madison that night, and chances are a lot of them will be quite drunk.
So, if you're looking for trouble, you will likely find it. You still might find it even if you're not looking for it. This is not something we're proud of at all, but thought you should be forewarned.
