***In short? Yes. ***
Absolutely! I was born and raised on the High Plains and isolated farms. We kept enough in the house for at least a two-three week blizzard.
Now in the Ozarks we still do the same. Several years back we had a horrible four inch thick ice storm. Power out for several days, yet we did well as we had lots of kerosene and Coleman lamps. Some had not been lit in thirty years.
A few years back we had a two feet snow storm. Again people were stranded, our power did not go out, but the roads were impassable. On the radio, with ONE station still broadcasting, we heard lots of phone in pleas for help.
People seem to have lost the ability to prepare for hard times.
I recall reading a story about that ice storm. Someone who owned a farm had a very large barn type building that they had converted into rec hall for their teenage kids. Pool and ping-pong tables, basketball goal, kitchen, bath, generator, propane heat. Since they had power they invited all the neighbors who needed refuge to come and camp out and it was one big party inside for a few days.
