Every October, farmers across the US harvest millions of pumpkins. Some make it to the dinner table in the form of delicious soups or pies. Others get transformed into spooky jack-o'-lanterns. Then there are the select few whose only purpose is to win weigh-off contests. There are numerous such competitions held nationwide. However, the most impressive mega gourds typically end up at the annual "Super Bowl" of pumpkin weigh-offs in Half Moon Bay, CA.
