Hello Professor Wolff. I think you'll appreciate this article if you haven't seen it already. http://www.npr.org/2016/12/27/503052538/when-residents-take-ownership-a-mobile-home-community-thrives
I saw this and have prepared a segment on it for my weekly one-hour radio and TV show, "Economic Update" that will be broadcast across the US starting this Thursday, Jan 5. Many thanks for sending it and please do so with future such items as you encounter them.
