I live in tornado country and we just keep a few gallons of fresh water just in case.
When our area got hit a few years back..without power for several days. My kids found out what cold showers are like. LOL!
I totally understand that. Often after a huge storm, water supplies are contaminated but that's not the case with the virus.
It also hit me yesterday when I saw some people at Costco that clearly don't have much in the way of resources, this is a middle and upper class thing. Poor people can't afford to spend $500 on groceries- they live week to week. When they do try to shop, there is nothing to buy.
