This is SO awesome! During the month of September, HBO will be running an authentic 1920’s Subway train on the 2/3 line in NYC to promote the new season of their hit show, Boardwalk Empire. They will even have brand ambassadors giving out complimentary MetroCards on the weekend of the show’s premiere. How dope is that?! You can catch the train on Saturdays and Sundays in September from 12pm to 6pm, making stopsat 96th, 72nd and 42nd street.
