No, as to the US Presidents
Yes, as to LDS Presidents. In fact I was about 2 yards away from President Gordon B Hinckley as he was hurried into the RS Room at one of the chapels in Springville. It was a Region Leadership Meeting and he was just coming in from Vernal from a morning session to Springville for an afternoon session and you couldn’t even see any fatigue from the trip. It was a very special conference and he was rushed out just as fast by his security.
Then Marie and I apparently walked right past the room where President Monson was waiting after our stake conference in April of 2009. We would have seen and met him had we waited just 2 or 3 more minutes. He was there to ordain his son as our new stake president in the BYU 6th stake.
Part 2: Which of the Presidents in your lifetime has been your favorite?
US President Ronald Reagan. He had the guts to see things how they were and act on them. And most of all he was proud to be an American and show it to the world just the opposite of our current guy in charge hiding behind the Arabs.
LDS President. President McKay was the President of my youth for 17 years and thus hold a very special place in my heart but I cannot say he is my favorite because each president as they become the prophet have a very special spot to the side of him. I almost feel a little ore close to President Monson simply because I am getting to know him better than any of the others because of sitting at the feet of his son who has learned so much from his father and sounds so much like him as well. So I do not have a favorite LDS President they are all on a pedestal far above any other men in the world except for the other general authorities. I have now lived during the Presidencies of exactly half of the church president. Also as a side note: We are also related to President Heber J Grant, if I remember correctly.
