In the case of the first two home football games, Parking and Security Services says it never became necessary to erect the barricades, and the lot was never full. It is anticipated that some of the future home games may have a larger crowd and the above reservation plan will have to be implemented. If you have specific questions, you may want to contact the manager of Parking and Security Services. Also, the fact that the University is not responsible for lost or stolen items. As you've said in your question, the parking fee is used for maintenance.
Maintenance includes snow removal as well as repairs made to the lots.
A portion of parking fees also goes to pay debt on existing parking structures and fund the construction of new parking structures on campus. If you would like additional information about parking fees, you may direct them to the campus parking services offices. If this is the case, perhaps the University should be a professional sports organization and get out of the business of education and health care all together. It boggles me that I couldn't park in a space that I have already paid for so I could come in and work as required by my employer in favor for someone here to simply watch a sporting event. The WG-1 lot is controlled by Campus Parking.
