To get a good idea of disaster situation is like,  turnoff your iPhones for a month if you can last that long.  And for an actual disaster situation go live with the homeless for 4 months leaving everything behind.  that is in a tent.  I don't know where they take a shit so I can't tell you.  Look around and what ever the homeless do of find water is what you going have to do too.  Be prepared for no fresh water for about a month or more since homeless going be in a disaster situation where even no more supermarkets to shop at much less no more money.   yes no toilet paper.  So live with the homeless should give a lifetime of actual situation we live in today. and oh yeah.  store some blue tarps,  buy one honda generator now.
