All the tickets were stupid tickets. 69+ in a 55 zone, speeding through a construction zone, no seatbelt, fart can...

Save the money with the speedo calibration. Speedometers are not required equip in Virginia, recalibration is taken into account by the judge, but you should know your relative speed (listen to the angry bees coming out of that fart can).

Expect to pay the fine for each ticket (max fine for the construction zone and seatbelt), then put on a stock muffler and take a pic to get that one dropped in court.
