Seriously.
People in hurricane, fire, blizzard, earthquake, and tornado areas do this all the time.
People need to look at it as having a pantry. Something people in the 30s and 40s had as a matter of fact. Only the 50s suburban living paradigm made it “weird”.
Sadly when they go online they typically see two types.
Preppers too often like to “show off” online because they are often female and it is treated as a “lifestyle” to fish for “likes”.
Survivalists are far too many times creepy loons and wannabe army rangers. Both have a haughty self-righteousness to them, and frankly turns people off because they are fatalistic nihilists. Too intense.
As a result, people feel like douchebags even trying, and they just dont bother.
People in FL prepare for a hurricane a day or two before it hits. Easy button food, water, plywood and beer supplies get wiped out.
