THE DEATH OF THE FERN
A "Fern", in original Amazing Race terminology, is someone who helps a racer find their way through their own hometown. It later became applied to anyone who helps a racer along the way.
The name is a homage to the original Fern, a young woman who played hooky from school all day to help Danny and Oswald (TAR 2, episode 5) navigate their way through Bangkok.
