As a culture historically obsessed with caravans, we glorify the flexibility of mobile living and imagine freedom to be found portable houses that can go anywhere and are not limited by building codes and conventions. In reality, of course, those who cannot afford to live in modern mobile homes and are forced to camp in makeshift groups have difficulty finding not only privacy but in many cases good access to clean water for bathing and drinking as well.
In some areas, local laws prohibit tent cities outright and residents are forced to hide in forests or otherwise undisclosed locations to avoid raids and harassment by police. In other cities, the sudden fact of hundreds of people living in a parking lot simply has to be accepted when shelters are already bursting at the seams. With repossessed homes, no income and no credit some individuals and families have no other option.
