I believe that polygamy is no longer practiced in the United States , as it is against the law.
Many LDS families chose to relocate to Canada and Mexico , where they could freely exercise their religion
I believe that there are many LDS families that continue in their religious practices in several foreign lands , without being encumbered by government CONTROL !!
So , I guess it continues ...
I KNOWthat polygamy is practiced in the United States, even though it is against the law.
