One good thing about making practical preparedness a part of your lifestyle is that you are prepared for quite a few of life’s routine emergencies. But, one thing you need to consider is the fact that you should not advertise it, but accepting that preparedness and survival for larger emergencies requires a certain degree of teamwork.
How much and what you are prepared for is something you should keep close to the vest. First, in a major emergency, those who are not prepared will see you as a target for getting quickly what they hadn’t bothered with before. They will demand you share with them, take them in, etc. Second, there are those who will not make demands and expect you to take care of them, as they are simply going to try to take by force what you have. Third, in a major emergency you are likely to have your reserves appropriated for the good of the people by various levels of government. It has happened before and will happen again. If they don’t know what you have and how much you have, it works to your advantage all around.
That said, surviving major emergencies requires teamwork. The simple fact is that groups do better as each brings strengths (and a variety of supplies/preparations) to the table. They can and should also provide safe places for bug-out at need. Sound people out, and choose wisely. Expect them to be judging you as well.
Years back, a friend was looking at just this situation. Through a mutual friend, he learned of a group that was into preparedness and looked into joining. He was quickly informed that he did not have enough weapons or the proper type of ammunition. In looking over their requirments and preparations, it was clear they were light on what I would call fundamentals. He thought a moment, and then informed them that no, he didn’t have all the ammo they required, but that he did have in addition to food a year’s worth (more actually) of toilet paper and they were going to have a hard time wiping their asses with all those bullets. And, by the way, he had more than enough ammo on hand to deal with anyone who tried to take it. They thought that over for a few days, contacted him to say that he had a point, and asked him to join them. He declined.
So, keep quiet but keep an eye out for good people to team up with at need. Make sure that they can be a safe haven if you have to bug out because of anything from a chemical spill to those pythonoids from Antares (who are just as big an group of assholes as the CCP) doing something nasty. Keep in mind that your location can be used if they need to bug out. Groups improve chances, but choosing the right group (or creating it) is essential.
