FAIRFAX, Va. - Research shows many serious car crashes are preventable by eliminating drunk driving, a cause that brought hundreds out to Lake Fairfax Park in Fairfax County (web|news) for the first "Walk Like M.A.D.D. Event.'

The participants turned out to raise money in an effort to combat drinking and driving and to support the families of those who have lost their lives as a result of drinking and driving.

ABC 7/NewsChannel 8 reporter Courtney Robinson was at the M.A.D.D. event in Fairfax County Saturday and talked with many whose lives have been changed because of drunk driving crashes in the Washington area. One such family says a drunk driver took the life of their son and 'Walk Like M.A.D.D.' provides him a legacy.

Among the pictures of those killed by a drunk driver is one of 8-year-old Joshua Adams.

"Typical Mother's Day morning and I had no idea that that was the last time I was going to see my little boy," said Joshua's mother, Darlene Adams.

On May 19th, 2008, Joshua and his mother were on their way to church when police say 22-year-old Rodney Martin rammed into the back of their van at a stoplight in Gainesville, Va. Police also say Martin was drinking and driving--a charge he'd faced before.

"I can't change that day; If I could, I would immediately, so now I have to live with this loss," said, Harry Adams, Joshua's father.

As a result, his parents and siblings are walking like M.A.D.D., taking part in the first walk for 'Mothers Against Drunk Driving' in Fairfax County. And by their side was the national president of M.A.D.D., Laura Dean-Mooney, who was made a victim herself when a drunk driver took the life of her husband 16 years ago.

"Many of us, myself included, have stories, but we don't want to have more victim stories. We want to end the process of drunk-driving. We want to eliminate drunk driving," said Laura Dean-Mooney, President of M.A.D.D.

More than 300 people took part in the walk on Saturday, raising money for the fight to eliminate drunk driving and hoping to bring change to laws and the decisions made by drivers.

"I want to leave a legacy for Joshua, so that this doesn't happen to anyone else," Adams added.

The driver who police say killed little Joshua will be back in court in February.
