Behind the scenes

 * At least in the real world, Pittsburgh is located in Pennsylvania.
 * Although in the real world the city's spelling was standardised as Pittsburgh about a century earlier, Bill's essay in The Pilot spells Pittsburg without the letter H. Since the word "conference" was also misspelled and other sources give the city's name as Pittsburgh, this article assumes the Pittsburg spelling was an error.
 * Autumn Mist does not specify which baseball team's games Wiesniewski would sneak into, but in the real world the city had multiple professional teams. In addition to the Pittsburgh Crawfords mentioned in Illegal Alien, the Homestead Grays and Pittsburgh Pirates also played in Pittsburgh in the years leading up to World War II.
