 FAIR: When Blake is leaving campus with Edison they take a left onto  a road out of the parking lot. That particular road, which runs  beside the library, is a one way road running the opposite way of  the direction they are driving. However, at the time "Necessary  Roughness" was filmed, the direction of travel on the road beside  the library was east to west as was filmed. The traffic flow was  reversed some time after the film was released.
