Finally, a horror story with some genuine horror.

I love the everyman feel of the narrative, and the references to reinforce the mood are spot on. You actually had me chuckling out loud in a few places, and the only other author to do that is Joe R. Lansdale, so you're in good company.
I also appreciate the cinematic quality of your style and would really like to see this story filmed. It would make a fantastic episode for a TV show, something in the vein of a more serious Tales From the Crypt.
My only suggestion is that it's so good, it feels like it should be a bit longer. Maybe adding to the sequence after Brian activates the USB drive. The trucker told him he was getting what he wanted, maybe things could look like they're starting to go his way, only to go south in a hurry.
But, yeah, I liked the casual dialogue, the common man references, and really liked the way you handled the gorier scenes, which are so often missing from the other stories on this site.
