On the road....at Columbus!  
That place is a madhouse.  I've been to alot of college football games, but there is something about being at an Ohio State football game that gives you the chills.  
I gotta say, this game is always close.  I can't argue with Iowa +7, however, there is no way they leave Ohio with a win.  Just couldnt see taking Iowa on the ML.
FYI, the buckeyes have covered 11 straight ATS.
