I think the parking problem has been one of the few things that has become easier for long time season ticket holders in recent years, but any lot that is available for first come, first serve basis anywhere close to the stadium is going to be expensive. If you arrive early enough and can park downtown or at the mall and take the available shuttles, you can save money, but they certainly add to the pain of getting out when it is all over. If you want to aim for something on or just off campus, also look at the Boy Scout lots across from DCH and near Coleman or the Soccer Field lots...
