The film is supposed to be set in the old West, but a sign appears in the background when Weston goes to prevent the bank robbery, announcing a Rodeo on May 1st 1932.
Marshal George Higgins: It seems mighty funny to me that every time this gang organizes a rodeo, their own men win all the first prizes. When it begins to look like an outsider is going to win, he gets sick. Two or three has even died from it.
