20/20 S2011E05 - Street Kids: A Year on the Road

They started out like any kids, full of hope and dreams - but now they're homeless and in terrible danger of slipping between the cracks. These kids are not living under a bridge, but under the radar -- part of a new under-reported type of homelessness -- surfing from couch to couch, from the beds of friends to the beds of strangers. For over a year, Chris Cuomo and his team have chronicled the terrors and triumphs of four such teenagers, all surviving largely on their own.
