Today marks one year since the Boston Marathon bombing, and this year, the city is making special efforts to remember those lost in the tragedy. Families and friends of victims participated in a wreath-laying ceremony near the finish-line site on Tuesday, with flowers and handwritten messages lining the street. During the event, Vice President Joe Biden delivered a few remarks, closing with some powerful words:
"We will never yield. We will never cower. America will never, ever, ever stand down. We are Boston. We are America. We respond, we endure, we overcome, and we own the finish line. God bless you all, and may God protect our troops."
Visitors also gathered at the Boston Public Library to view the memorial exhibition Dear Boston: Messages From the Marathon Memorial, where flags, objects, and handwritten notes for the victims have been collected and put on display. Boston College students paid their respects over the weekend, too, organizing their own "bandit marathon" a week ahead of this year's race, with students running the exact same route as the actual race.
Since last year's marathon, Boston Marathon bombing survivors' inspiring stories  have made headlines, and earlier this month, people saw love in the wake of the tragedy as a Boston Marathon couple got married  ahead of the one-year anniversary. Rebekah Gregory and Pete DiMartino were dating at the time of last year's marathon, both of them suffering injuries, and Pete popped the question last October. The couple won The Knot's 2014 Dream Wedding , and on April 4, the sweet couple said "I do" in a gorgeous ceremony that was streamed live on the site. On Monday, the newlyweds will join thousands of people participating in this year's marathon, with Pete pushing Rebekah in her wheelchair. Pete told Glamour , "It'll take some of the strain off my legs. Together we're both stronger." Rebekah noted that running the race will serve as a form of closure, adding, "This whole situation has made me appreciate myself, and us, more than ever. I've got huge scars, but at the same time, every time I notice them, I think, 'I'm a survivor.'"
