I reached out to the ticket office about parking. You can get a season parking pass for $100. They have availability in Ramp 4, Lot 3 (library), Myrtle Lot, or Lot 65 (which I assume is Finkbine?).
Ramp 4 is almost across the street from Kinnick but getting out of that ramp after the game is a bitch and tailgating wouldn't be all that fun. Library looks intriguing since it won't be far from my sons dorm, I'm guessing there is tailgating going on. I know tailgating goes on in Finkbine, I've parked there before. The walk from Lot 3 and Lot 65 are about the same, so I'm leaning towards the library. Does anyone know if that lot is fairly easy to get in and out of, from the maps it looks easy. The walk doesn't bother me, by the time my car has moved down 1 level in that ramp I'll be at my car in either Finkbine or Library.
