Ever since I read "My Lead Dog Was a Lesbian: Mushing Across Alaska in the Iditarod -- the World's Most Grueling Race" (the book is better than the title, by the way) I have been fascinated with dog sledding. If you're itching to be pulled along by friendly Siberian huskies from the Arctic Paws dog sled team, learn the art and history of mushing, and take a turn at controlling the team on a short ride, Stone Hill Center in Williamstown is hosting Family Day, an afternoon of dog sledding, snowshoeing, snow sculpting, and sledding on Jan. 25 from 12:30-3:30. There will be a campfire and hot chocolate - and hopefully, snow. (Lack of snow will cancel the event; check online or call 413-458-2303 to confirm.) All the activities and admission to art galleries are free. Stone Hill Center, which opened in June, is part of the Sterling and Francine Clark Art Institute. It houses art galleries and the Williamstown Art Conservation Center.
