"Look at all these people here. Everybody here has been touched by a drunk driver somehow," said Lori Moran, who lost two young daughters in 1990.
Some who came to the event ran and some walked, but they all moved forward together.
"I knew a neighbor many years ago who lost her young son to a drunk driver," said Lindy Jones. "For the memory. I'm doing it for the memory."
No one's loss deserves more attention than others, but a recent tragedy has drawn a lot of public attention. Dan Schulte's family was torn apart last March by a driver police say registered a blood alcohol level three times the legal limit.
Schulte's parents were killed trying to cross a Seattle street, and his wife and newborn son were severely injured.
"I'm trying to be optimistic about it all and look ahead and not back," Schulte said. "The more you get the word out, the more people know it can happen to you, it can happen to your family."
It happened to Moran 23 years ago on Valentine's Day.
"Kami was seven and Nicole was four," she said of her two daughters.
Moran has channeled her grief into action, speaking to school kids and lobbying for stronger DUI laws.
Schulte hopes Sunday's event can help save others from the pain he and his family is now enduring.
"Whatever we can to to prevent these tragedies in the future, I think we should and increasing awareness is a big part of that," he said.
