Western or Prohibition-Era skirmish game suggestions

My wife isn't terribly interested in wargaming, but I think it's a setting problem. She's not really into fantasy or sci-fi or into the history of war but she does love horror, westerns, and the history of the 20s (she loves Call of Cthulhu TTRPG and themed board games). Are there any western or 20s themed skirmish games? Horror isn't necessary but definitely a plus.

Fast play is preferable.

Edit: Thanks for the fast suggestions everyone. I'm trying to sell her on Dracula's America, sounds right up her alley :)
