If I might make an observation... Some of the people we see on the news digging through dumpsters and foraging for food may have been well prepared
but living on the ground floor or, prepared but in a way that this sure didn't anticipate.
For instance... A wood stove is outstanding if you're in a rural area or in an urban area with open/no regulations on such things. In Kansas City,
St. Louis or Memphis....such a thing may not be as possible or even realistic. I can't help also note the obvious quandary about a wood stove in an
epic flood situation.
For those not in Rural areas or others where that is not realistic, I have another suggestion for the Title idea. Buy 12v. Buy everything...12v. My
advice comes from most of my life being in a truck and 24/7 living wherever it parked that night, whether services existed on an Exit Ramp or wide
spot 100 miles from a town or the best Truckstop in America (Little America, Wyoming.
On 100% 12v power, I had a compressor driven fridge, Microwave, toaster oven, DVD/TV Combination, Sandwich maker, Coffee maker, mapping system and
laptop/tablet power, among other things. 12v is available in every vehicle in the nation and portable with a dolly for people of almost any physical
shape to remove a battery and use it alone. Solar trickle charges for slow charging..or more powerful solar chargers will keep them juiced and running
indefinitely if someone has them in sequence of use vs. charge to rotate them (and the fridge is pushing it without an idling engine to charge a bit
every few hours)
Just my two cents when shelter in place may not be available with all the pre-planned options, if at all.
