Hi Scott,
This is my favorite line,
"Alma and Junior could not have invited more of the people that Ennis hated if they tried." Nice story. And are you headed toward Ennis meeting someone new in Casper - say the stable owner? I think you have the right tone in your story. You may consider a beta-reader to help just a little with smoothing out the flow of words. Keep going.

ps Mendelson wrote the wedding procession for a friend of his, not Wagner. Wagner would be a bit overwhelming for a little church wedding.
