Who Shaves the Barber? - S1-E7
Factual error: The scene which supposedly takes place in Fargo was obviously not filmed there. Fargo does not have any skyscrapers that tall.
Factual error: Peggy and Ed are hiding out in a cabin "just outside of Sioux Falls," but are somehow also close to Mt. Rushmore. Mt. Rushmore is near the western border of SD, Sioux Falls on the eastern border, more than 340 miles apart.
Factual error: Parts of this season take place in St. Cloud, Minnesota. The problem is, the St. Cloud they portray has significant skyscrapers. St. Cloud is a town of about 80,000 people with no large skyscrapers.
Factual error: The arm on the phonograph is on the wrong side. It should be on the side near the viewer.
