The cars and trucks that passed this way threw their trash out into the forest without pause, faster than the gleaners could pick them up and find new uses for them. The waste had always struck Maceo as a disgusting mystery, but now, it made sense. The indestructible plastic bottles and wrappers that rained on the ground were not merely trash, but seeds--diabolical harbingers of the alien ecology of metal and plastic and advertising that had already swallowed the coast. It was a hostile invader that no one else seemed to want to fight. The dead-eyed souvenir-hawkers at Coba sold the products the signs foretold; beside the road to the ruins of the once-sacred ceremonial city, a looming image of golden arches promised a still-greater ritual awaiting them in Valladolid--the devouring of machine-made ghost-food. Maceo could not read the words on the billboards, but he knew that they sought to infect their victims with the virus of desire.
