I've thought much about Bugging In over what could be a long period of time. Some issues I have struggled with are having enough energy to heat my current location. By that, I mean; will I have the wear with all to harvest the forested land around me without getting my firewood taken from me by force. Currently, I have a pellet stove. Practical for today's environment, but with a total power outage and zero transportation there would not be a supply of pellets or electricity to drive the igniter, auger and fan motors. Therefore, a conventional semi air tight wood stove would be a better choice although; not perfect. I've thought about LPG, but that would run out as would any other fuel source. What happens when those resources dry up, are inaccessible, or your heating equipment becomes inoperative. I've thought about using tarps to wall off a smaller portion of my home to extend the time my fuel would last but the end result is that I will have to learn how to live and survive without heat and only natural light. Dressing more warmly, conserving resources, reading during daylight hours, keeping a low profile, staying dry will all become much more important. My plan is to start acclimating now.
