City of Truths

Imagine you are on planet Trulie with only two inhabitants, one that always tells the truth, and the other that always lies. You reach a fork in the road with a sign to the City of Truths. Unfortunately, the road sign is down. Fortunately, a Trulian appears from nowhere. What question do you ask him to find the way to the City of Truth?
