Zombie nerds. They probably had the flyers already made up for this. There was nobody creepier than the zombie nerds, college guys who not only watched zombie movies and read zombie novels and played zombie video games, but actually formed clubs and collected zombie-killing weapons. Gun shops around there actually stocked zombie targets, and special zombie bullets with glow-in-the-dark tips. Not toy bullets, mind you. These guys would go out in the woods and train and shoot and defend to the death their right to stay in childhood until age thirty-five.
