Pennsylvania may have Punxsutawney Phil, but Illinois has its own weather-forecasting rodent: Woodstock Willie, made famous by the movie “Groundhog Day,” which was filmed in Woodstock and released 30 years ago.

For half a century, “Peanuts” creator Charles M. Schulz entertained and educated the masses with didactic characters that fans came to know as real people—with real causes. From pollution to recycling, the “Peanuts ... Naturally” exhibit at the Peggy Notebaert Nature Museum embraces Schulz’ forward-thinking ability to confront global issues through the hearts of children and adults alike.

Find out why Woodstock, Illinois -- the backdrop to the classic movie Groundhog Day -- is reliving the same day over, and over, and over again.
