They already tried Boulder, which is extremely cold. I guess the zombies or at least the Inklets have adapted to cold weather? It really perplexes me, how did Hawaii get hit early? Something to do with the whole ring of fire or earthquake zone?

When Victor and Saul went to Inglewood those ground cracks reminded me of earthquakes (yes LA native in the da house).

Barstow is a small ish community for Southern California, but everyone drives through from LA on the way to Vegas.
