The author is apparently unfamiliar with trailer parks.
My city is full of trailer parks. It's a consequence of Idaho liquor laws. The number of liquor licenses is based on population. Building trailer parks was a way to bump up the population numbers quickly. Today, they are full of classic white trash. My wife is a police/fire/EMS dispatcher. She can cite the names and recurrent criminal behaviors of many of the trailer park inhabitants. It's a regular Peyton Place. My wife tried to attend church when we first moved to the area. It wasn't long before she realized that she knew the dirt on nearly everyone in the ward. It's worse than being the ward bishop. Not at all a comfortable place to be.
