One thing we got from the CDC guy, a timeline. He said in the one recording that it was 193 or 195 (something like that) days since the virus got out and 160-something since it went global. But, we don't know exactly when he made that recording in relation to our gang showing up. Still, that's 6 months which is damn fast to wipe out the world.
As for the gang not picking up rifles, that's a huge, tremendously HUGE, pet peeve of mine. It seems that nearly all movies and TV shows do the same thing. The hero is walking around with limited weapons and ammo and never picks up the guns lying around. And when they do, which is rare, the film/show always treats it like a surprise to the audience hoping we'll have that "Oh, ****, he totally owned that bad guy that thought he was all out of ammo and **** by picking up the dead guy's gun and totally using it! ****, that wus ******' awesome."
