Bob is 62. He's unemployed, and he sometimes calls our show when he's listening. But here's where Bob's story is different: he calls us from his van. Where he lives. For the past 5 months, Bob has squeezed his entire life within the rectangle of his Dodge Caravan - bed, food, stove. He says he never expected to be living in his car, but that a whole new community of people - suddenly jobless and homeless - are also living behind the wheel. Who are these people? How do they get by? And how does one go from a full-time job to suddenly living alone in a van? Bob lets us into his van and tells us the secrets of surviving when you're homeless in Las Vegas. Rebroadcast.
