Boston Mayor Marty Walsh has declared April 15th—the anniversary of the 2013 Boston Marathon bombings—as One Boston Day. Said the Mayor, "One Boston Day will inspire all of us to come together as the community we are and share the spirit of Boston by giving back. April 15 is a date that has come to stand for our city’s deepest values. I hope everyone can mark this day in a way that is appropriate and inclusive for each of our experiences." Tomorrow, Mayor Walsh will help raise banners along Boylston Street to honor the bombing victims and survivors. This new tradition will serve as remembrance of that day's events that left four dead and over 260 wounded.
