A flyover isn’t exactly a visit. I get flyovers from the USAF every day, I don’t consider them visitors. And the reason some households are one mom/one dad is because dad hasn’t been ‘good enough’ to get awarded more wives. They’ve got to have at least 3 to get anywhere good in the afterlife. Of course, the downside to that is if you displease the leaders, you get your wife/wives and family taken away and reassigned to a more deserving man.
So much for ‘family values’.
According to the records of "the bishop" which were presented at the hearings, only 1/3 of the families are not currently polygamous. That includes some young men who are probably not old enough to have garnered the respect necessary to get another wife.
