During the episode when investigating the Missouri State Penitentiary they put a picture of John Brown up and said it was Friebug Johnson. Historical accuracy is important. There have been a few other historical inaccuracies throughout the series but it is still an interesting program. As a high school history teacher I still would recommend the series. This thing wants me to write so many characters. So I will continue to write. Also, have you noticed that most of the abandoned structures are NAZI. WW2 was a global event that changed the future of mankind. When teaching US History I spend 2 months on WW2. Now I have enough characters.
