Lastly, there are no “EXPERT” preppers that I know of! Just as there should be no one directing, suggesting or quantifying anyone’s efforts toward being ultimately prepared. We are all in different stages with any of the attributes required to be our best, not someone else’s best. There are just way to many factors that have to go into the equation for one person to know it all. I learned a long time ago to never point out a problem without recommending a solution. I feel survival training through this venue is best served by not casting doubt, mistrust and pointing out scary gaps in plans being worked on. Instead, Train skills, knowledge and attitudes. The “How Tos”, “Where to Find Useful Info” and just the considerations of the attitudes. Let the individual prepper decide how it fits into their specific plan.
For personnel who are flying over large bodies of water, in additional to wearing a survival suit over cold water, a survival kit may have additional items such as a small self inflating raft to get the aircrewman out of cold or predator infested waters, flotation vests, sea anchor, fishing nets, fishing equipment, fluorescent sea marking dye, pyrotechnical signals, a survival radio and/or radio-beacon, formerly a distress marker light replaced by a flashing strobe, formerly a seawater still or chemical desalinator kit now replaced by a hand pumped reverse osmosis desalinator (MROD) for desalinating seawater, a raft repair kit, a paddle, a bailer and sponge, sunscreen, medical equipment, a whistle, a compass, and a sun shade hat.
Civilians such as forestry workers, surveyors, or bush pilots, who work in remote locations or in regions with extreme climate conditions may also be equipped with survival kits. Disaster supplies are also kept on hand by those who live in areas prone to earthquakes or other natural disasters. For the average citizen to practice disaster preparedness, some towns will have survival stores to keep survival supplies in stock.
To me, the best option is to store emergency food. How much? If you have none, store enough for a few days. If you have enough for a few days, get enough for a week. How much you store depends on what time frame you think you're at risk for having to be completely independent. The early settlers of the southwest liked to store enough food for a whole year and still do to this day!
