WH: Whether Philippe's walk between the Twin Towers was witnessed by anyone down in the street really didn't matter. Philippe once secretly put a cable across a 2,400-foot ravine and walked across it and danced on the rope. Only a farmer who was driving his cattle at sunrise realized that someone was there. He rushed into the village to wake a policeman. And when they came back on a motorcycle, there was no Philippe, there was no wire left.

PP: But the cows remember.
