Just in case, TreeHugger looks at the things you should (and shouldn't) have when the lights go out.
For heading to the hills in a hurry, you can fill your Voltaic backpack with a wind-up charger for nights or living in caves. For water, small units like the Lifestraw may be useful. Don't forget a Fire-fly stove but for quick energy when on the run, nothing beats a Clif Bar. An eco-camp kit might be useful, although a solar powered tent might be a bit heavy. A Bikamper Bike tent might be a better choice. Load it onto a good solid Jorg and Olif and you are on your way ahead of the crowds. You can add a bike trailer if you need more stuff.
Don't forget to read up about food foraging and Michael Pollan has a lot to teach about hunting in the Omnivore's Dilemma. With luck, you will last until Halloween when the clocks move back to where they are supposed to be.
