The bicycle magazine VeloNews revealed the shocking truth behind the Tour de France: The fields of sunflowers lining the tour's route were the result of a secret program of genetic manipulation designed to produce flowers that would exactly match the color of the yellow jersey of the Tour de France. Unfortunately, these genetically engineered sunflowers were also prone to fungal infection. Those concerned were "embarking on a nationwide campaign to warn farmers about the risks involved in accepting cash, seeds or other considerations to plant flowers along the route of this year's Tour."
