A sure sign that the chilly weather is finally taking its toll on nature is sleepy local wildlife. Kids will learn all about hibernation as they craft bear, bat, toad and hedgehog masks (10am–1pm) to the accompaniment of storyteller Rama Mandel's tales. In the afternoon, little ones will don their masks and learn to waltz with the help of instructor Jody Kruskal (12:30, 2pm). Afterward, take them home for a little hibernation of their own. All ages.
