Agritourism is pretty popular right now, with farmers trying to add a little extra cash to their corn cribs by inviting the public to the farm to hang out in pumpkin patches, take haunted hay rides, pick apples, pet goats and pig out on pizza. One of the most popular draws, however, are corn mazes, which seem to get more and more elaborate each year. This fall, one of the best is a stunning maze in Wisconsin that is a tribute to the science of geology, with a fossil trilobite as the centerpiece, reports Christine Mlot at Science.
