Back when the Earth was young, back in 1958, an earlier incantation of this conundrum went something like this...

You find yourself in the middle of a island inhabited by two friendly but divergent tribes of indians - the Blackfeet and the Whitefeet. The Blackfeet never tell the truth in words or deeds, but the Whitefeet always tell the truth.

You need directions to excape to the coast as most of the island is covered with quicksand but a taboo of both tribes requires them to cover their feet. They all agree to draw you a map but the only questions that they will answer will be those about the color of their feet.

How do you get to the coast?
