"The fair-minded readers among you will doubtless have felt stirring of outrage on the part of the woodchuck; why should the groundhog receive all the fame and glory, when woodchuck is a perfectly acceptable variant?"
Anyway, woodchucks have enough fame already (how much wood…?).
Meanwhile, what it (that groundhog in Punxsutawney, Pennsylvania) sees on Groundhog Day (today) is not necessarily what you get. Here’s the official data from the National Weather Service (NOAA).
There are even more groundhog forecasters in the running such as Octorara Orphie of Quarryville, Pennsylvania—competition right next door to Phil—Staten Island Chuck from the Staten Island Zoo, Unadilla who hails from Nebraska, Buckeye Chuck from Ohio, French Creek from West Virginia, and the Cajun Groundhog from Louisiana. Ridge Lea Larry is a "stuffed groundhog" from Western New York, and the Tennessee Groundhog of Silver Point, Tennessee, is actually someone dressed up like a groundhog on a motorcycle.
