You don't need to "know" anyone to get a decent parking spot at Iowa. Just like at Iowa State, if you're a season ticket holder, donor, and/or I-Club member, you can park pretty close to the stadium - right next to the press box.
It's the same way at ISU. The more you've ponied up to show your support, the closer your parking pass.
Agree 100 percent - priority seating and parking are given to the big donors.
