Based on this crude but honest assessment of the general public's affinity for the common bicarbonate, you'd be surprised by how much survivalists are into it (#2 on the list of "things for preppers to hoard"). They must expect some pretty serious hankerings for tasty leavened baked goods, or they have extensive phobias about the funkiness of their nuke survival backup plans.
The survivalist hard-on (yep, and I'll do it again, too) for prophylactics untouched by chemical pleasure-enhancers is the result of drilling deep (told you) into the magical properties of our latex friends. According to our research, these flexible, durable, waterproof wonders will be as much of a deciding factor in your dystopian longevity as fire and can openers.
It’s bad enough being injured or lost in the wild but things really get bad when the weather closes in and you can’t get a fire started to stay warm and prepare food and hot drinks. That’s where Ultimate Survival Technologies’ Wetfire Tinder comes in. Developed specifically to help you get a fire going in the pouring rain if necessary it’s without a doubt essential survival gear.
The most dangerous people in a survival situation is the gang of outlaws who only want to take what they need and don’t care about what happens to the owner(s). The hardest to know what to do with, and for, is the individual (person or family) who has done nothing to prepare for emergencies or disaster. It’s hard to want to help someone who does not, and will not, help themselves. But it’s endemic to our society – it’s all about big brother taking care of you, or “the government” being your friend. It’s about entitlement. It’s about not caring about other people, only yourself/family. They are the 2 true dangers to preppers.
This group consists of people who live in tornado, hurricane, flood, wildfire, earthquake or heavy snowfall-prone areas and want to be prepared for possible emergencies. They invest in material for fortifying structures and tools for rebuilding and constructing temporary shelters. While assuming the long-term continuity of society, some may have invested in a custom-built shelter, food, water, medicine, and enough supplies to get by until contact with the rest of the world resumes following a natural emergency.
With goTenna you use a simple smartphone messaging app as a platform for sending SOS messages along with your handheld hunting GPS coordinates should you need emergency help. You can also use it to chat with emergency services so they know your exact condition and can prepare accordingly. It’s off-grid survival gear at its best and could be the difference between life and death.
Each type you listed (save a couple) will have its uses in a community (group if you will), generally having a small trusted group with each having several skills in the various fields (prepper, homesteader, and survivalist) I believe would be an effective team, though as each group works together would it not be best to ensure that each has overlapping skills in case of injury, death, or other reasoning they can not fulfill their duties?
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!
