Seat cushions are OK as long as they do not have a back rest. If you have the blankets, you may want to consider bringing them. The wind can be pretty brutal. Donor lots open at 7. General public lots (G lots on the map) open 6 hours before kickoff. If I can still do math, is 8:30. There are hardcore groups that show up right when the lots open. But I expect slow filling lots as people skip the hotel room and drive in from out of town in the morning. Here is the link to the game day policies. Call the ticket office if you still have questions or just want to make sure. https://cyclones.com/sports/2015/3/2/GEN_2014010120.aspx Safe travels.
