PARIS (AP) — The Tour de France is like a good bouillabaisse, the traditional Mediterranean seafood stew. Take out one ingredient, and it does not taste the same. The Tour starting on Saturday has all the ingredients in place: —A nervy first week on treacherous roads. —Towering mountains passes to climb. —The grandest of finales up 21 hairpin bends to the Alpe d'Huez ski station. —Four genuine contenders, the most in years, all at the top of their game.
