If I were you, I'd make sure you have at least a one month supply of food and water, two full tanks of propane and batteries for flash lights.
Buy a bunch of those little solar lights, put them outside. Power goes out, bring the lights inside, back outside they go in the daytime to recharge for the next night. Cheap ones from the dollar stores work just as well as the expensive ones.
Good idea. I hung solar lights on 2 porches two years ago and they work like a charm. I also have battery operated candles that can be set to go on and off at specific times.
