On the fourth anniversary of the Boston Marathon bombings, hopeful messages sprang up around Boston and the rest of the country. The third annual One Boston Day was recognized with charitable acts and remembrances of those lost when two bombs exploded near the finish line of the 2013 Boston Marathon.

Volunteering and blood drives were among the activities Bostonians participated in on Saturday. Others, including former Vice President Joe Biden, took time to convey messages of perseverance in the face of tragedy and terror.
