First, the story. I'm with Listener in that I struggled at times to recognize who was speaking, also there were several places where I wasn't sure if a particular statement had been dialogue or narrative from the Sheriff. I think a lot of that stems from the reader using the same voice for both narration and dialogue. Not that it was poorly read, but varying one's voice from narration to dialogue, even if just slightly, goes along way to helping the listener differentiate between the two.
The tale itself was interesting and I enjoyed it. I liked the delayed revelation of the Sheriff's identity because it kept me wondering for the whole story what his stake was in all of it. I do agree with Unblinking that there was little emotional involvement, though. Part of that disconnection I think comes from the hidden identity of the Sheriff. As much as I like that part, not understanding his stake in the tale makes me not care if he succeeds or fails. I wonder if there would be more emotional payoff if we were told up front that he's the sheriff and we understand what he's fighting for.
Second, Congrats Dave. I have two myself and we're planning a third sometime in the near future. As for name suggestions, Cutter McKay is my never-to-be-used name of choice for my own son. I came up with it years ago, Cutter being a video game character's nickname, McKay is my own middle name. Unfortunately, my wife hates the name and refuses to name any child of hers "Cutter". SO, I have been forced to take it as a sort of pseudonym, naming at least one character in every story I write some variation of the name. For instance, for those who read my EP flash fiction contest entry, there was judge McKay in the courtroom.
That said, I think people should just start naming their kids with gamertags and save them the trouble later on.
