Personally, I’ve moved most of my investments into money market funds and plan on buying the dip, just like the multi millionaires. Other than that, I’m getting stocked up on shelf stable foods, and trying to get to know my neighbors a little better.
Stocking up on food and supplies.
Water jugs and a hand pump if power becomes unreliable
Easy prep meals that keep. (Small cook times but store able / propane time to cook ratio sort of thought)
Propane camp stove.
We just sort of double or weekly orders and rotate the oldest stuff up into the house from the basement.
Full range Medical kit with gsw treatment options and tourniquet
If extended black outs are something we are faced with you should own a firearm or have a big barky boy (dog lol). Rolling blackouts multi day can lead to some chaotic situations in people.
