Boolean Logic, The Gorge of Eternal Peril

Here is the scenario. You are in a room with two closed doors both look exactly the same. There are two other men in the room with you, one standing in front of each door. One door leads to "The Gorge of Eternal Peril.",  The other door leads to Kansas and you want to avoid the Gorge and go to Kansas.

You are told of the two men standing in front of each door that one always lies and one always tells the truth, but you don't know which is which and both men know where each door leads.  You are also told that they know each other and they know if the other one always lies or always tells the truth. You are further told that you may ask each man one question (It can be any question for either). What questions do you ask the two men to find out which door you want to go out to get to Kansas?

Try and figure it out for yourself before you look at the comments, because someone may already have. If you've heard it before and already know, don't tell until someone figures it out.


Update - to make it easier to  think through, draw a picture, draw a square room with  two doors and the three of you.

Update II - Looks like no one can answer it check the comments and I'll answer it tomorrow sometime. Wonder if The Super intelligence Vox can answer it? If you seen it before and know the answer go ahead and answer it.
