Factual error: When Ray and several others are riding in an automobile they pass underneath a railroad bridge. Passing over them on the bridge is a modern day container type train, a train of the era that the film portrays would be made up mainly of boxcars, tank cars, etc. not shipping containers.
Factual error: In one scene, Ray is frying chicken. He proceeds to flour a couple of pieces and drop them in the pan containing hot grease. There is a piece already in the pan that is done, so Ray holds out the pan to his friend to take the piece of chicken. His friend reaches into the pan, removes the piece of chicken and immediately bites into it. Fried chicken that has just been removed from hot grease cannot be immediately eaten. It has to be removed and allowed to cool for a few minutes. The friend would have burned his fingers as soon as he reached into the pan and then would have burned his mouth as soon as he bit into the chicken.
