The St. Patrick's Day Parade in South Boston is back in all its green glory this Sunday, but the party had already started Saturday in Southie, where streets and bars were packed with people. For many, this year will be their first time. “First time for all of us to watch this parade, and we’re so excited, we’ve been down since Friday," one man told NBC10 Boston. "We’re having a great time. Boston's the place to be. We love Boston.” For others, they consider themselves experienced partiers in the city.
