Right now, the best way to deal with a parking ticket is to plead not guilty and wait for the court time. The city have too many cases now that they usually just drop it. I pleaded not guilty 2 years ago, the court time never sent to me.
The reason for this is to stop residents parking their car along the curb, but allow visitors to park. No body will stay between 1-3am, unless they live here. Usually this will prevent some house owner rent the rooms to too many people and harm the value of the houses in the community.
