The Johnson family is traveling to new places. This time, they fly to Boston for a cousin's wedding, and Jennifer Johnson wants her kids to experience some of the town's history while there. Taking a subway for the first time, sampling new foods, and exploring impressive landmarks like the Paul Revere House, the Old North Church, and the USS Constitution anchored in Boston Harbor add fun and discovery of American's early days to this family adventure. Six-year-old Katy visits some famous ducklings in the Boston Public Garden; ten-year-old Bobby helps solve a crime and rescue a new friend; and older brother Joey reconnects with Barby, a girl he met a year earlier, and finally attends a Red Sox game at Fenway Park. These sites and events make their five-day trip to historic Boston one they'll never forget.
