what i'm trying to say okibi is start off with unpredictability, :) I mean if the news is reporting all these grizzly murders then wouldn't the cops be out in full force trying to catch the killers? And zombies aren't particulary smart so where would they have been hiding? You could start the story with a outbreak during the middle of the night by a umbrella/mystery person who wants to sabotage the umbrella company or is seeking retribution against the town, etc. There's different ways to achieve the story, just try to think of it from the girls perspective ;)
