Omaha

Not much is said about Omaha, except that Bobby Singer and Rufus Turner went on a hunting trip and something went wrong. Bobby stated in the episode ... And Then There Were None that him and Rufus either sit there on their thumbs or they go in guns blazing. Rufus replied "Like Omaha?". Bobby has a negative response to that state as he tells Rufus to screw himself and that is was low bringing up Omaha.
