In Tuesday night's episode of ABC's Nightline, host Cynthia McFadden introduced a story about a "normal" community of polygamist families that live in Centennial Park, Arizona. She also went on to plug for the new National Geographic show Polygamy, USA: 

To some, having more than one wife might sound like heaven on earth. But just imagine the communication skills required the potential for jealousy. And all those family logistics well they might just seem overwhelming. No one knows exactly how many polygamous live in this country. Most live in secret. There's been a lot of news about the followers of Warren Jeffs and alleged forced marriages of underage girls. But tonight we meet a community with a twist the women choose their husbands, not the other way around.
