The group hosted a "First Class Subway and Black Tie Beach" event on Sunday. Dressed to the nines in formal attire, they feather-dusted a Blue Line train and offered passengers snacks. Then, they soaked up the sun and built sand castles at Revere Beach.
Costumes this year included classic comic book superheroes, princesses from Frozen, and a new Boston Strong character. Plus: Sean Astin shared memories from the Lord of the Rings set, and Jason Momoa of Game of Thrones fame smooth-talked a fan in Dothraki.
