This summer, I spent 5 days in an FLDS community (NOT the one run by Warren Jeff's, my ex next door neighbor). It blew my mind, and put me in a position to scrap 90% of what I thought I "knew' about the fringe religions of Mormon. I am extremely well traveled, have stayed with many cultures (like Massai, Fundamentalist Muslim), but this one is a highlight of my life.
I am not of any religion. Definitely not Mormon. Very definitely not Polygamist, though a lot of my friends are from polygamist families.
Though I will try to top this experience with a swing off the Corona Arch later this month. (Worlds Largest Rope Swing--on YouTube)
