When looking at abandoned places, I often think, ‘how sad’, and, ‘if only it could come back to life’. This place? Not so much. This is the secret Soviet city of Gudym, which once held enough nuclear weapons to wipe out half a continent. And during the height of the Cold War, had things gone south, they would have been aiming just across the fence, where a short 200km away, is the United States of America.
