When on a vacation, my wife and I stopped at the winter home of Brigham Young at St. George, Utah, when passing through. A church elder gave us a tour (we were the only two visitors, so we got a private tour) which was fairly interesting. If I recall, Brigham Young had one wife who lived year-round at the winter home, even when he was away at his main home and other places with other wives. At the end of the tour, the elder gave me a copy of the Book of Mormon. After we returned home to Florida I actually read the whole book.
My opinion of the members of the Church of the Latter Day Saints is that they have some strange beliefs, but that they are for the most part really good people.
