Mickey, there is a huge difference in short term compared to long term survival techniques and methods. Before attempting long term survival plans, it is good idea to try the short term solutions first for a while, maybe a couple of weeks to get aclimized to a particular situtation. Then you will have a better concept of long term survival. Remember much of long term survival depends on just what you do in the short term to prepare for the catrostropic survival. Finding our what is needed for short term survival in extremely important for long term existence. Also, remember that catostropic survival is absent of law and rules, so one doesn't need to worry about water rights or depend on permits for power. Also, I would not choose a place without some hydro or very good adequate supply of water. A small water wheel will supply some power, even if minimal. Any construction effort to save time for hunting and planting while increasing productivity will eventually merit strong consideration. Even an electric DC light bulb will last for years. I rarely replace DC bulbs and have gone to the AC coiled fluorescent screw in bulbs at home. Those last about 10 times longer than regular bulbs on dirty or inconsistent Hertz generation for AC. The work done by night from a DC bulb will increase your productivity for long term survival by not having to render fat for candles or oil in wick lamps. In a catrostropic survival situation, products we currently enjoy daily will be scarce or non existent, so take advantage in the short term for any labor savings ahead of time. One can last a long time if prepared for catostropic events, but he must be able to use what tools, supplies, and forethought for the short term as to take advantage of the time needed to stabalize his chosen location with food, shelter, tools, clothing, medical, water, energy, and edibles storage.
