Being that CO is Alferd Packer country, the name is inescapable here. We have a dining hall named for him at CU, and I thnk he has a museum dedicated to him somewhere. I live just a few minutes away from where he's buried. And yes, I've been to see it. I'm that much of a nerd.
The storyline about his horse, Liane, refers to the fact that Trey's fiancee, Liane, cheated on him shortly before he made the movie, and naming a slutty horse after her was his way of getting back at her.
I know, I know way too much about the movie... :P
