I also come from a mountaineering/rock climbing background and during the years when I was active in mountain rescue the guiding principle was not too much, not too little, but just right - food, meds, equipment- it was all in a back pack that never left my immediate vicinity. I was constantly tweaking that pack and its contents,changing for the seasons and the varying conditions. It was essentially a bug out bag.

I try to follow the same practice in preparing for foreseeable situations now. Having an overabundance is just as bad as having too little. Even when you have the right amount, it must be organized and accessible when needed. I often come up short in that endeavor.

'When it comes to electricity, I am a solar fan. For years I have worked at a park (Channel islands) where solar powered our outlying ranger stations. no noise, no fueling, drastically less maintenance, and plenty enough juice to handle necessary functions. I can see the day when my home will sprout solar panels, but for now I have a couple of mobile panels and a variety of power packs. I can keep portable lights and cell phones up and running. Fortunately, I don't have to worry about AC (most of the time, anyway).

I have plenty of camping gear. Mrs. Hikermor thinks I have too much, especially fuel. When the earth moves for us, I will just camp on the property and begin salvage and reconstruction.
