During the early scenes with Bubba, Forrest tells of the fact that Bubba mother served shrimp, her mother served shrimp, her mother.....etc. During these flashback scenes of Bubba's mother, grandmother, and great-grandmother watch the window facing the yard behind the table as they are serving. One window shows a 69 Camaro , even thought it was around 1965 when this flashback took place. In fact, when it shows the car Forrest is talking about Bubba's grandmother. She and the man she is serving, are dress as if they were in the earlier part of the Century.
