"Don't blame Montana!" he said. "Don't ever blame Montana!"

I feel that this is the most important quote of the novel, because it shows how proud the family is of Montana and how much they really loved it after all the events that transpired there. Through everything that happened, from their family being destroyed to Marie and Frank dying in the very house they lived in, the Haydens still love Montana and are not ashamed of anything that happened there. They don't want the blame being left on anyone or anything but themselves. Wes was born and raised in Montana and he doesn't want people to think that what happened is just a "wild west" type of thing, and laugh it off as such. After all these years the family still feels as strong as they did back then, and although they brush it under the rug it will never truly be gone. This quote shows how the Haydens have taken full responsibility for everything that happened in the novel.
