Other than "This is off-topic", all I have to say is good luck.
I was once tagged for reckless in Caroline County as well. When I went to court, there were also a bunch of other people there for the same. IIRC, the judge did not reduce many of the charges. My fine was $250 for 90.
If you have a clean record, you might be able to get it reduced because you're not as culpable as someone whose record is not spotless. If this is a first offense, take a "driver improvement" class. That'll look favorable. If you're a VA resident, you'll get 5 plus points on your record if you take a driver improvement class.
ETA: Ask the trooper for their RADAR calibration. The RADAR gun has to be calibrated within the preceding 6 months prior to your offense. If it was not calibrated within the 6 months preceding your offense, the case can be dropped. However, don't count on this, as most LEO do have their calibrations.
