Point at one of the forks and ask "Would you tell me to take this fork to York"?

Correct fork:
  * Liar would say not to take it, but would lie about it so her
answer would be "yes, I would".
  * Truth teller would say to take it, and would tell the truth so her
answer would be "yes, I would".

There's a truth table and boolean logic in there somewhere… :)

But, you know, it's Saturday afternoon so I might've missed something...
