I really miss the "Good Ole Days" when Monroe County numbered everything in the 51 series back in the 1970s, based on the old "Emergency" TV show.
51-8 was the northwest sector patrol car
51-24 was the Dundee contract car.
51-25 was the Petersburg contract car.
Then after Sheriff Harrington retired, the new Sheriff went to the correct numbering sequence, which was 58 rather than 51.
