EDEN, N.C. -- "Don't drink and drive. Don't ruin your life and someone else's. You can't go back after the fact."
That's Kevin London's plea.

He's sharing the sobering reality of what happens when you drink and drive on Twitter, one follower at a time.
"I can't be silenced. And I think if we all become silent when something like this happens, we don't have these groups and organizations to lean on to push towards trying to put an end to drunk driving," said Kevin London.
He added, "You hear it on the news, and see it but until you put a face with it, it's hard."
Staring back from Kevin London's Twitter page are the faces of his daughters, Taylor and Meredith London.
The sisters were killed last summer in a car crash. The driver was their friend and police say she was drinking before she got behind the wheel.
"You try to fix it, but there is nothing you can do," explained London.
He added, "It's a new normal now for me so I feel like I have to try to prevent this from happening to someone else."
Each day he tweets out a picture of his daughters or news about another DWI crash.
Each post pleading for people to help end drunk driving.
"I don't know how this is going to end up, things are just kind of small right now."
He has nearly 90 followers - but his reach is wider than the web.
He speaks to youth groups, students and parents sharing his loss and hoping to "make a difference and change someone else's course along the way."
"There are just so many ways you can stop it before it happens," explained London.
This summer, Kevin was asked by Mothers Against Drunk Driving to meet with the US Transportation Secretary about ways to eliminate drunk driving - including law enforcement campaigns Drive Sober or Get Pulled Over.
