Power generator. I have a Briggs and Stratton 3600 watt portable. I've never used it, which is a good thing because I've never lost power. But I know a couple of people here in Iowa that have lost power and lost their entire stock. For me it's just peace of mind to have one, then I don't have to sit back and watch everything freeze to death from the cold. If your considering buying a generator though don't skimp, a cheap one is not going to work when you need it, go with a honda, briggs and stratton, or Yamaha, brand names.
