Roadside Picnic - Wikipedia, the free encyclopedia

"The name of the novel derives from a metaphor proposed by the character Dr. Valentine Pilman, who compares the visit to a roadside picnic. After the picnickers depart, nervous animals venture forth from the adjacent forest and discover the picnic garbage: spilled motor oil, faded unknown flowers, a box of matches, a clockwork teddy bear, balloons, candy wrappers, etc. He concludes that humankind finds itself in a situation similar to that of the curious forest animals."
