Wisconsin can probably still play at the old Dane County Coliseum (or whatever corporate name it goes by now) and it is plenty big enough. I think around 8 or 9000 for hockey and Wisconsin rarely draws that anymore (again, notwithstanding whatever the phony boxscore numbers are). I think they played games there within the last couple of seasons. Notre Dame fans who were around back in the WCHA days probably remember that place. Great college hockey atmosphere, fueled in large part by beer!
