Continuity mistake: Two different cars are used; a smaller Mercury and a larger more powerful Lincoln in the hill scenes - both convertibles. Side trim gives it away too.
Continuity mistake: In the close-up shots where Tacy is driving and fighting with Nicky, the sideview mirror is tilted up against the windshield to accommodate the camera angle. However, in the distance shots, the sideview mirror is tilted down and out to where it should be for safe driving. Moments later, in the closeups of the park and the filling station, the mirror is again tilted up against the windshield.
Continuity mistake: When Nicky leaves the trailer the night before the long haul up the mountain, he is wearing a brown leather jacket. When he returns the next morning, as Stacy is supposedly getting rid of all the rocks, jams, etc., he is wearing a blue jacket.
