Last night during the Walking Dead episode “New Best Friends” I happen to notice something during the scene where Daryl and Richard were arguing. They were standing next to a truck trailer with a mural on it. I took me a while to catch but then I realized: That is the trailer from Smokey and the Bandit! Do anyone else catch that? It must be a homage to Smokey and the Bandit. I think the series was supposed to have originated just outside of Atlanta, which was the ultimate destination of the Bandit and Snowman in the film.

There may also been some significance to the gift that Rick gave Michonne when they were leaving the landfill. It was an ornamental statue of a cat or something like it. Perhaps they will elaborate on that in a future episode.
