Cash and checks are accepted. There is a map in the parking brochure that explains which lots are reserved and general parking areas. Park in a lot that is posted for your permit. A large general parking lot is located at Saunders Fieldhouse. Another general parking lot is located at 12th and Kennedy, across from the Campbell College Center and Lowell Heiny Hall.
Parking is also available around the dormitory areas.
When in doubt check the signs posted at the entrances to each lot. They explain the type of permit required and the hours of enforcement. It depends on where you are parking. You will certainly be ticketed, and may be towed away. I sold my car and got a new one.
