You may want to look back for prior threads on this topic where this is been discussed, but to the best of my recollection visitors tickets are usually in these areas:
family and VIPs in the first few rows of sections V and W ;
other fans in sections Y1 through Z1 (South end zone in front of the Fieldhouse) and
section AA ( this is at the very south end of the upper deck and must be the seats that Herkmeister is referring to above ) .
My wife sat next to an Iowa Alum who had played in the 1957 Rose Bowl in section B but I don't know how he acquired his tickets.
There are high seats but few bad seats. The big screens are well situated .
