The mayors of Boston and New York today announced the traditional Super Bowl bet between municipal leaders, but this one has a tourism twist: A lucky family from the winning city will be treated to a free trip to the losing city. In a joint news release, Mayors Thomas Menino and Michael Bloomberg said today the family (of up to four people) will get a “Super Tour” in one of their cities that will include two nights in a hotel, dinners, performances, and even tours of local breweries. The winners will be chosen from an online drawing after the game. If the New England Patriots beat the New York Giants, a family from Boston will fly to New York. If the Giants win, a family from New York will fly here.
