If a catastrophe happens, and it is prolonged, I wonder how many of us have considered the enormous amount of knowledge and skills it will take to survive a major calamity, and it's after shocks. I was doing some thinking about this on and off for some time now. Especially for groups of people, if i belonged to such a group, what would my specialty be? Of course this happens sort of naturally even on a camping trip, somone naturally assumes a leadership position (whether they know anything or not) and many people just do what they are comfortable and familiar with, if that is cooking, gathering firewood, the list goes on. As far as my training and experience is concerned, major assets for me are my medical and trade skills. I have several others, but those are two good examples. Finding others who have developed skills to a high degree that can cross train you is a tremendous added benefit, and it helps you to acknowledge the skills you lack. What is your specialty? What is your trade and training and what tools do you need or have that fill that specific niche???
