We enjoyed the show for the most part. But even though we suspend dis-belief with horror and sci-fi (because if you don't just change the channel) we still can't believe how in the world LA is empty.
Impossible.
DC area was pretty empty as well where they were in Alexandria. In TWD they explained that they had evac'd a lot of people out of DC, but they didn't make it so they setup shop there. Maybe big cities got all of the military support which got rid of a lot of the roaming zombies and people bailed on the cities (we saw traffic jams on the overheads and in Atlanta). Also, as we saw in that one arena, they locked people in there. Maybe lots of arena's in cities with lots of people who stayed.
I don't know, but I think big cities probably had tons of people bailing.
So many ways out of LA it isn't even funny. Also, at this point people likely have enough stuff in their houses to stay alive for a few weeks, so maybe a lot of people just holed up waiting for news.
