The Neshoba County Fair has been held each year since 1889 in Neshoba, Mississippi, northeast of Jackson, southeast of and close to Philadelphia, MS.
More on the fair here.
In addition to entertainment, a midway, a watermelon-eating contest, and horse and mule races, there are political speeches. I videotaped several this year, including the speech of William Winter, former governor of Mississippi.
