 These are often people who sleep in their cars because they simply cannot afford to pay the rent on the salary that they're making. The ones we interview, the homeless people, are more likely to be chronically homeless and to have mental problems and so forth. But even those individuals have what we call kind of income-creating activities, whether it's recycling cans, passing out flyers for a local business. Sometimes it's sort of underground economy. It could be selling goods.
