Rob We just got back from the lights and figured it out in the first twenty minutes of being there (Car tail, and head lights) 5 miles North of Paulding the road climbs a two mile long hill, which also is directly in line of sight of the dead end on old 45 (the view spot). All you are viewing are cars going up and down the hill. We confirmed this the next morning with a $6.98 mirror purchased at Wall Marts in Houghton. We dropped two people off at the point of view and two people drove the mirror to the top of the hill middle and bottom of the hill. The observers were able to see the mirror flahes on broad day light on all three locations. It all cars and no mystery.
