How the Trailer Park Could Save Us All

It's very interesting to me how neatly this matches up to my generation's dreams about all living in a forest together. It boils down to a pretty harsh indictment of America's suburban design, doesn't it? Like... houses that aren't bigger than people need. Enough garden to putter in. Walkable neighborhoods so you can see your friends. None of this is rocket science, and yet it's so proscribed by law and markets!
