Well, at my school I was notorious for parking in faculty parking... to the point where they booted my car after like 20 tickets.
Anyway, you could try contesting the ticket where you pay the fine, but if there's a lot of paperwork/hassle then it might not be worth the effort for $10. The university struck me a deal where I paid off all my tickets at once with a discout and got the boot taken off. That car payment seems rather hefty for someone in school btw.
