When we have good storms ...the power goes out on the island from downed trees and lines...
Then it is at least the next day before it is fixed ...
hence most residents here have multiple alternate options for such emergencies...
back up generators for their freezers...solar...wind...small hydro electric off of streams...wood stoves..pellet stoves...passive solar heating...etc.

For myself...
I have more than enough land for a very decent garden to feed enough for a few families...the soil is great..the stream's excellent for irrigation..and it's output is good enough for my electricity needs until the dead of summer...so it isn't flowing for only a couple months then..I have had a local expert look at setting it up..it is the most viable of all the alt electricity generating options.
it should run me about 5000 - 10000 ..for a set up...that will give me more than enough electricity output I will have a surplus to sell back to the provincial electricity company.
My wood stove is a nice modern airtight...and I have a second stove that is suitable for a shop or second cabin...
I am on my own well...
I am on my own septic ...
So I am set up pretty good...

Hahaha..if society falls apart...My island community will do fine...
worst case is if it gets really bad ..move further north... to say Lasqueti ...smart bunch there..they are even more resourceful ...in fact they have their own currency ...really ! hahaha...
Anyway...
If bombs are dropped ..
My hillside isn't facing the continent ...so I think it wouldn't be too bad for me...
shouldn't be too bad period...

But really...if bombs start dropping...
unless you have a hermetically sealed bunker with enough... food (saying it doesn't go bad in the first 10 years) ....water ...filtered air ...and a waste disposal system ...and power to run it all for the rest of your natural life...and hope you don't get sick...too...
then really..
Bombs start falling...we are all hooped.
It is only a matter of how long after they drop...is all..

But any situation shy of that ultimate...and I am looking pretty good here
