I used to live in Missouri. Looking at the artwork, it seems pretty accurate.
From the campaign:
The Pariah Missouri Role-playing Sourcebook will plug and play into whatever RPG system you want to use. It will have all the background, characters, NPCs, maps and campaigns needed to create a rich world. Think of it as a campaign book that will have everything the GM needs to add Pariah to whatever rule system they enjoy. Included will be stats for all the major characters and everything you need to play Pariah! Full-color with art on every page. Over 64 pages!
