The latest PD-X configuration has been driven with great success. Even the curious police officers who stopped to query PD-X were pleased with what they saw. Although there was a bit of discussion at the toll booth as to whether PD-X should pay auto or motorcycle fare, motorcycle fees were paid . There were many unexpected thumbs up on the road. PD-X is a beautiful site to see in the driveway at home and soon to be back at the airport for some flight time.
