Groundhog Day Predictions for a Year, All Animals (Groundhog-Day.com)

groundhogday/predictions-by-year

Every Groundhog Day prediction on record for one year, 1886 to the latest published season: for each animal that made one, `shadow` (1 saw its shadow, six more weeks of winter in the legend; 0 no shadow, early spring; null no recorded prediction), the day's notes and the animal's slug, name, city, region and country. Early years hold one animal; recent years hold 80 or more. A year outside the range, such as a future one, is refused as VALIDATION. Data from Groundhog-Day.com, trimmed to those fields and served by Eden Engine; not an official Groundhog-Day.com product.
