Living Beneath Las Vegas
Las Vegas was once the very definition of a boom town. But the boom went bust and as foreclosures rose, so did the city's homeless population, from 12,000 two years ago to 14,000 today. Yet there are fewer than a thousand beds in shelters, forcing many to seek shelter in the labyrinth of flood tunnels that snake beneath the city.
CBS News correspondent Seth Doane, left, is seen here walking the tunnels with journalist Matt O'Brien, who wrote a book about this elaborate subterranean world.
