Corrected entry: In the scene where Daryl Mootz pulls up in his SUV for the rain-making event, there is a shot of the SUV with a front Kansas license plate. Cars in Kansas only have rear license plates. (00:12:55)
Corrected entry: This whole episode takes place six months after Valentine's Day (August) when the episode aired in January. Another thing wrong is that Mulder and Scully are on the case when they're currently off the X-Files. The mayor even said that the FBI gave the case to them.
Correction: The date an episode takes place does not always have to coincide with the air date. The case they are sent to investigate by the FBI is a fraud claim against the Rain King, not an X-File. They both still work for the FBI.
Correction: Cars in Kansas do have front license plates if they are personalized just like Daryl Mootz's RAINKING license plate.
