Oh, I almost forgot. Make sure you have the means to fell trees and turn them into firewood manually, without fuel. Great for heat, cooking, light, etc...and in case I didn't mention it, FIRST AID supplies and skills as well as learning what remedies can be found in nature for various maladies. Medical skills of this nature alone can guarantee you everything you will ever need from those that don't have them. Oh yeah, oil lamps/lanterns are really good to have as well as antibiotics and the ability to make soap from stuff like ashes and cooking grease....Learn how to harvest game with traps, snares, bow, slingshot, etc. Whatever doesn't make noise......and on and on...
Speaking of lighting, I was thinking about those solar lights that line a walk way. My dad has a few. You could charge them during the day, then bring them in at night.
