Mr. Menino remained a creature of its neighborhoods. He spent his whole life in Hyde Park, where he was born. He spent his days ambling along the city’s streets, talking with residents, reporting potholes and rarely missing a ribbon cutting. In a remarkable achievement for a big-city mayor, he met more than half of Boston’s 625,000 residents in person, according to polls. He left office with approval ratings at an astronomical 82 percent.
