And the couple in that article were traveling in a van, not exactly "living in a van" just to save money. Also, they stayed in places where it was legal to park and camp. Note also that they were camping in places where there were restrooms and water available. They were NOT parking in neighborhoods and using sidewalks or yards as bathrooms!! If someone had tried to park overnight in my neighborhood when I had young children, I would be calling the police as often as many people do in such situations. This is the reason why so many communities are making it illegal to "camp" in neighborhoods where sanitary facilities are not available and where they are not set up for camping.
