Funny how we never learned or heard about the klingon neutral zone in the original series! In fact it's only reference seems to be in the movie The Undiscovered Country! We hear of the Romulan neutral zone quite a lot in the show and we even learn of their home planet and system but not the Klingon world! in TNG it was to be called Kling as you all know but they changed it to Quo'Nos and left kling as an area of their planet!The closest we come to seeing klingon space seems to be Trouble with Tribbles as it is set near to the Klingon border! Does anyone else have anything to say about this?
