A lot depends where you live. For me, if I just stayed home, nothing much. I have enough food to last 3 months and endless supply of water with a 10k gallon water catchment system. I just picked up plenty of propane, gasoline and diesel. I live in a remote area of Puna with no close neighbors.
Just 10,000 gallons?
I have 34,000. Tanks are full.
I also have Hamakua ditch water for my animals and garden.
That is good for 10,000 gallons per day.
My neighbors are way to close, but they are good neighbors to have.
Doctor, lawyer, Rancher, heavy equipment owner, et al.
Big island people prep for this stuff. Oahu people try to take it all away.
We are lucky they can't walk or drive here.
I'm just insulting Democrats, I like everybody else.
