As Charlie and Wesley are walking away from their broken down car, they argue about the picture of Betty that Charlie keeps looking at. Wesley grabs the picture from Charlie's hand and rips it into 3 pieces. Charlie runs back and picks it up and puts the pieces back together. Only now it is only torn in 2 pieces.
Between seeing the sign for the Grand Canyon and arriving there after dark, Charlie and Wesley are briefly shown driving in Arches National Park. This is a couple hundred miles northeast in Utah, and can be identified by the Three Gossips on the left side of the road, and the Courthouse Towers on the left.
When Betty drives away from her town, she is shown passing a "welcome to Kansas" sign which is on passenger side of the road facing her, even though she later says it is the first time she has ever left Kansas.
