At times like these that I simply hunker/bunker down with my own resources-plenty of food in fridge/freezer/cold room and I'm an excellent cook-hotpot,BBQ etc.People are just selfish crazy  when power /wifi etc  outage hits-besides restaurants ,stores are in crisis mode-I don't add to it-even gas stations BTW always have some cash-on hand in different denominations for times like these.
