There was some controversy among the group about the shooting cornbread scene. My father thought it was unrealistic that a man in as precarious and risky a position as the Rooster would allow himself to get sloppily drunk. I thought it was unrealistic that they would shoot all their cornbread.
My interpretation of the ending is that Rooster sent Maddie to Memphis to pick up his body. If he had wanted to see her, he would have suggested the show in Greensboro.
