The fallacy, of course, is that anything between you and where you

Can you get out of the city?  "State"?  Country?  etc.
Without knowing the extent of an outage -- and the
reliance on power that exists for each step up the
ladder -- it would be hard to generalize your capabilities
from "simple tests".

 Well, the power outage was "total". :-D

Yeah, but you don't know which services (up the chain) may
have their own *local*/private backup systems.  E.g., I doubt
your hospitals were without power (?)  The extent of backup
beyond that would be something you'd have to know, in advance.
