My family did fine during the water and power outage but then again growing up on a farm I think we are more prepared then most.
You can get a propane heater for less then $100 at tractor supply at 750 watt inverter that you can run off your car to run most things at Walmart for $49 and some aqua-tainers. In addition to that we have a bi fuel generator which we never even had to go to as the inverter was enough.
Best quote of the whole incident was when my 6 year old daughter asked me: "Daddy, is the power on or off?" as she was watching a dvd with lamps in the house on, running off the inverter, house heated by propane heater and wife cooking in the kitchen on a camp type stove. We did run low on water as I only filled one of the aqua-tainers but we had bottled water as a backup that we never had to use.
