Don't forget your money and credit card. We do not have enough medicine to store some away. Not all of us have family elsewhere, let alone in the truth. Do not forget that I will be 20 miles away at work, with collapsed bridges and riots in between me and home. There are some good people both around home and work I would team with until I could connect. BTW, the .22 will travel with me.
The usual way to take care of disasters is to get someone else to put people up in their homes, donate time and money to any rebuilding, and DO NOT specify funds for anything in particular.
There was a time during the depression that Rutherford stated "we" would all travel in caravans with clothes that never wore out (like the Israelites), and cars that never ran out of gas.
Being prepared is a good idea. But no one has ever told me what is the big danger here (no ocean or big rivers, volcano, earthquakes. And the "group overseer" is older and in more need than I.
