Drive NEAR the court, and park where they probably won't tow you if left overnight. I don't think they'd even notice if you parked at the courthouse though, they don't really keep tabs on stuff like that. Usually stuff like this, you just pay the fine or get an extension, bring SOME money as good faith. I've never heard of them arresting you at the courthouse for this, if you are driving they can if you get pulled over, but I've been let go a couple of times when this happened just due to a clerical error. You should be fine.
