For years, Boston watched other cities throw the kind of outdoor holiday market that draws crowds in the cold. Snowport, in the Seaport, is the answer—a two-month run of handcrafted gifts from local vendors, hot chocolate, iceless curling lanes, and the watchful eye of a furry mascot named Betty the Yeti. Free, easy to find, and gone by January. The closest Boston gets to feeling like a European Christmas market.
