At age 8, his parents took him to Dallas on Nov. 22, 1963 to see JFK's motorcade. There is a photo of him in Dealey Plaza being hoisted over his father's head just moments before the assassination. He discussed this in several interviews.
Very sad to hear of this and shocked. Tombstone is one of my favorite movies. Frailty, Apollo 13 and Aliens are also really good. The Hatfields and McCoys was also a great mini-series. Wow.
