When Jean and Griff are first shown driving away, the car is shown going down a gravel road. Griff asks her mom about a couple of towns when the car breaks down. The next shot is Jean, standing outside on a nice paved two lane highway hoping to see another vehicle. The camera shot shows the highway far into the distance with no sign of a dirt road.
In the very next scene it is dark and Jean and Griff are asleep. Jean hears the motorcycle and yells at him. He tells her that the car is done for and offers to take them to South Dakota. Jean tells Griff to just take what she needs, and it shows them filling up her backpack. As the motorcycle rides away leaving them at probably a bus stop, they now have many large bags of clothes with them.
When Crane is driving Jean home from town there is no rear-view mirror in his vehicle. However, when they arrive at Einar's ranch a few minutes later, a rear-view mirror is clearly visible on the inside windshield.
When Einar takes Mitch his morning pain shot and coffee, before leaving Einar puts a dark brown mug with a straight rim on the night stand but a little later it shows Mitch drinking from a tan cup with a fluted rim.
In the scene where the truck with the grandfather (Robert Redford's character) and the young girl inside is coming back to the farm at night you can see a human watching the scene, and a piece of equipment at the end of the scene in the bottom right corner.
