Choo-choo! Kids love trains. And at Holiday Express, they can actually climb onto one—an old-fashioned steam engine. Besides the locomotive fun, children can also visit Santa and indulge in treats. The event will be held on December 3, 11 a.m.–4 p.m., at the Roots of Motive Power Yard and Engine House in Willits. During the event, nearby Mendocino County Museum will hold its Holiday Program, at which kids can try their hand at writing with ink and quill or typing on an old-fashioned typewriter, and do other crafts, too. Both events are free. For more information, go to tinyurl.com/2cx6usjr.
