Going on day 4 with no power.
Here is what I did not have:
gasoline
Enough cash
A freakin radio ( I know, stupid)
A switch installed in my furnace to hook up to a generator
No need for ammo, but based on the lines at the gas station, it would not be far away...if there was no end in site.
I have plenty of food, but the stores are open a few miles away. But they had no produce.
Just a quick list from a pretty tame emergency. Good practice. The list grows every day.
Been there, done that! I recently bought two nice batter operated radios. I find that I use them quite a bit. You can get a decent multiband for about $25.
Had one of these for years, AM, FM, SW. No Batteries required!
When I wired my house during building I wired in a few junctions just to power up critical circuits.
There is another trick for getting power to circuits but I'm not telling. If you don't know circuitry already you could get dangerous:)
