You weren't able to shower, or heat your home. You threw out all the food in your fridge. You couldn't turn on the lights or the TV for two weeks or more, and you clung to cellphone power like life itself.
Some are still without power because of superstorm Sandy. And it is expected there will be other storms in which Long Islanders are bound to lose power again.
Unless you have a generator.
