Take it for what it's worth, but if you know me I have been around since before Voat - same name. I am pretty low key I think but judge for yourself.
Anyhoo, my husband got a call from his brother, former Commander in the Navy. He is hearing that things are going to get a little crazy in around four weeks and that people should have four weeks of food and water just in case. Be able to sterilize water too. Something to do with panicking deep staters trying to block ports and food supply. This brother is really smart - many engineering patents to his name in his post military civilian career. Retired now but was literally considered intellectual property when his company was bought and sold, etc. The regular Joe brothers tend to think he's a right wing nut, and he is absolutely right wing but so am I so that doesn't really dissuade me. Not gonna lie sometimes I think he's a little out there. But he still has friends in high places and he knows people think he's nuts but feels it's important to share. Thought I should too and let people do what they want. His point is if you spend $600 to stock up and nothing happens, you still have $600 worth of food and water. If you don't and you end up really needing it....you don't.
I find that 2 liter soda bottles or the heavy duty squarish juice/tea containers are easy to clean and I fill them and use every inch of freezer space with them. Also the lids seal good for storing them under beds, under sinks, garage etc. They say 3 gallons per person per day.
I store water in every empty milk jug, juice bottle. Plan on boiling it before consuming. Or use to flush the toilet.
When there a storm forecasted.... I'll fill the bathtub with water. It sounds silly I know, but my sister has lived through some big disastrous storms and having extra water was a big help (for flushing the toilet) ....
