well, around here.......I'm not in the city...(Nashville)--this is the country...rednecks --you can spot em a mile away-they all drive trucks, they all own guns, they have a deer head on their wall (come to think of it, so does my best friend) the confederate flag is branded on their denim jackets and decorates the back window of their pickup.....hill billies on the other hand.....are like you described in your text......you don't ever see em....unless you got lost in the hills (something you don't want to do!)
Oh......and they always have names like Bubba, Junior or Bubba Jr....
