Lines miles long for gasoline:
The government cannot possibly provide the basic needs for a city the size of New York. The bottom line is that these people were warned, ignored the warnings, did not prepare, and are now paying the price.
Some sensible steps to take:
Have a least a weeks worth of food and water in your pantry. Rotate it. Store what you eat, eat what you store. A container of Mountain House freeze-dried entrees( they can last up to 25 years) and a couple cases of bottled water can save your life.
It goes without saying that food that needs refrigeration or freezing won't work. Canned, bottled, freeze-dried, dehydrated or vacuum packed is the stuff you need to stock up.
The chances of water and sewage service stopping is very high, so get one of those five-gallon plastic buckets with a potty lid on it, the kind you put plastic garbage bags in. Store it in your closet.
When the plastic bag starts filling up, replace it and toss the smelly one. This lack of this one item can make your emergency experience miserable beyond words.
It doesn't take much to be prepared. but it does take a bit of effort.
People who are truly prepared often go far beyond these basics. They have generators, weapons, fuel, medical supplies, bedding and clothing, but what is needed to survive a weeks worth of shortage is just not that much.
So just go do it. None of us cen predict when we'll need it. Maybe never, but having it stored away sure as hell beats dumpster diving.
