How did Sulu know the location of the peace conference?
Okay, sorry if this has been answered already, but this is the one question---and the most annoying plot-hole----of a movie I've always loved that I never got an answer too:
How did Sulu know the peace conference was going to be held at Camp Khitomer?
(FYI: the novelezation of Star Trek VI clarifies--and answers---the plot-holes many have found in this movie, except this one. And it's the one I remember people having the most questions about since the movie's release.)
