Living in the Yukon we sometimes talk about what would happen to most &quot;city folk&quot; if their world fell apart with no supermarket and electricity.<p>Most of us hunt our own meat, grow our own vegetables, build our own cabins and get our own firewood. Tons of people up here are already living entirely off-grid.<p>We all agree, our biggest problem would be lack of gasoline to run chainsaws, and none of us really has a solution to that. Cutting firewood by hand would be doable, though it would be a full time job to get enough for the winter. A decent size house will burn through roughly 10 cords in a single winter.
