Apparently I'm guessing cuz I had a 6:30 class last sem, the parking outside fills up really fast cuz there are a lot of adults and drivers that go to school. I paid a few times parking behind the library, then I didn't pay near the end of the semester. Some people say they don't check at night cuz security can't ticket you, only the officer or whatever. Plus when I bought the parking ticket, most people don't take the ticket cuz it's useless anyways and leave it in the machine, but when I bought mine at night there wasn't any at all. I guess you can always occassionally park in the lot cuz its so much closer
