The description on YouTube of this video says it best.....what a cool, touching video.

On April 21, 2014 the world's focus will return to this great city to watch the 118th Boston Marathon. As usual, runners will take their places at the 26.2-mile mark, while friends, family, and the people of this iconic city line the streets to cheer them on. The memory of last year's heinous and senseless act will not shy runners or spectators from celebrating this annual sporting event that welcomes participants from all over the world. Yet, we will all stand in remembrance of the beautiful people who lost their lives and those who were gravely injured in the tragedy. In pain we found love. We grieved together and chose friendship over hate. We honor the brave men and women who tirelessly worked in the days after the bombings. This short video is dedicated to the great city of Boston and its people, and especially to the victims Martin Richard, Krystle Campbell and Lingzi Lu, as well as to MIT Police Officer Sean Collier who died in the line of duty. They messed with the wrong city. We choose to be Boston Strong and WE WILL RUN.
