Children rejoiced and travelers let out a collective groan as the year's first major snowstorm, dubbed "Hercules," closed public schools and grounded more than 2,300 flights across Chicago, Boston and New York City.

The storm was so intense that Massachusetts —which received up to 2 feet in some areas — temporarily closed its state government, while New York and New Jersey declared a state of emergency.

While many resigned themselves to ride out the weather in the comfort of their warm homes, here's how some folks (and animals!) spent their snow days.
