Continuity mistake: On the way to Ishpeming from Chicago the filmmakers point a camera out the window of their car at the reflective wheel hub cover of a truck riding alongside them. The reflection shows that they are in a small white sedan. Yet the car that they are eventually shown driving in Michigan is a black Subaru station wagon. (00:34:25)
Continuity mistake: The Google Earth Streetview route shown through downtown Chicago (I-94/90) is not part of the computer-plotted route from O'Hare Airport to Ishpeming which they used. It would have been a long detour from the suggested path laid out for them. (00:34:30)
