It is also the 4 year anniversary of Jake Christensen's debut as Iowa's opening day starter. And the 4 year anniversary of the day Hawk fans drained Soldier Field of beer and had so many Hawk fans tailgating that every portapotty in a 1 mile radius was overflowing with urine. Man, that parking lot looked like a warzone when we left it. Vomit, urine, trash, empty beer cans. What a sight.
