11 year-old Zach Bonner finally made it to D.C. Thursday, climbing the steps of the U.S. Capitol and completing his walk from Tampa, Florida – a 1,225 mile trek – on behalf of homeless children.

Zach's Little Red Wagon campaign continues to raise money and awareness of homelessness and already has a new goal on the horizon, walking from Tampa to Los Angeles.

"You don't have to be all grown up. No matter how old or how young you are, you can make a difference. There's all kinds of things you can do," said Zach, who has a YouTube video describing his campaign.
