NAPLES, Fla. - Bob Votruba is a man on a mission. His hope is to spread kindness one city at a time.

"To me, that's how we change this world. One person at a time, but the hundreds of millions of people in this country and across the world," said Votruba.

His story began five years ago, after he watched the Virginia Tech tragedy unfold on television.

"I said something's wrong here, I want to make a difference, I don't want to watch an another event go by without doing anything."

Now he spends his time on this bus and this bike, on city streets, and inside schools.

"As I stop in schools I'm finding these kids have much too much in the way of adult-type things to deal with at far too young of an age and it affects them their whole life. We're trying to let kids know, hang on to your life with all your might, it's gonna get better," said Votruba.

He started his journey on October 22 in New York City. He'll travel for 9000 miles during his one year ride.

"I'm just one guy with one dog, riding a bike, living on a bus, trying to make a difference," said Votruba.
