Came back through this town returning from Mexico. Police car pulled alongside us about 2:30A.M. and drove there for some time. We were going to the speed limit, everything was in order. He would pull ahead, back up, pull beside us and was very distracting. We came over a hill where the speed limit dropped to 55mph. and right behind us was a police car. The only thing he could find was that we were going 4 miles over the speed limit and he ticketed us for $140.00. Came back from another trip from Mexico this past week early in the morning and the police cars had flashing lights everywhere. They're 7 hours from our home close to Dallas, so I couldn't go back and fight it, but I do hope this helps someone else.
