PA Speeding Ticket

What is the name of your state? Pennsylvania
Anyway to fight this?... I attached the ticket to view, all personal information was crossed out. I was leaving my college on the main road of this town. I am going back friday to see if there was a speed limit sign from the college street to where the cop was sitting. Not sure if there was or if it was after the cop. He used a robic sg-808 (stop watch) It was a single lane road. for one lane on the right one lane on the left going opposite ways. The cop went again on coming traffic because there was a car in between me and him. The main information on the ticket is: Nature of offense: speeding
