My son lives in LA County, Sierra Madre.
He has three days of supplies and never expects to use them. He is a PhD and of course knows everything, lol.
He says all my doomsday scenarios (always) has him down here in my garden at the end of a hoe. I told him not to worry that as atuned as he is (ahem), I'll have to phone to tell him his neighborhood is being over-run and that he'll be eaten before he gets here anyway.
Good luck Red.
My local Walmart just started selling the Augason Farms Emergency Food Kits, the 200 meal Dinner and Breakfast kits of 6 #10 cans with everything from scrambled eggs to mashed potatoes, cheaper to get the kit than the individual cans, so I bought two Breakfast and one Dinner, that 18 cans plus I grabbed a can of powdered honey. Each kit is 6 cans, thats 200 servings.
They are just flying off the shelves up here in Alaska.
I am stocking these up in my restored camping trailer with everything needed to be totally self sufficient.
Three days worth of goodies is a bit light, but Sierra Madre is an easy enough place to get out of. There are some places in L.A. County that are difficult to get in an out of; miles from a freeway, no large secondary roads, and/or limited routes through ranges of hills or mountains.
