I vote the saddest moment ever is when Ike dies. I cried and cried and cried. I couldn't even watch reruns of that episode, because it upset me so much. Apart from that it was such a good episode. Can't wait til March 21st!
I agree w/ you that the sadest episode was when Ike died and how hard it was for Buck to deal with it. I also agree that the other saddest episode was when they stopped at Lou and Kids wedding for season 3. I would have loved to see more episodes with them married and the life after the pony express for all of the characters.
Very sad moment, but my saddest TV moment was when Sgt Chris Lorenzo was killed on the cop show Silk Stalkings. I hated Ike being killed but I could still watch the show because of the larger cast. Chris was one of two main characters on Silk Stalkings so that made the show unwatchable to me after his death. And it was so sad because he was killed in front of Rita (his pregnant wife who used to be his partner and best friend). Oddly, enough the guy who played Chris was one of the guest stars on an early episode of the Young Riders.
