One interesting notion within the prepper community is the rule of three. In other words none of us should be scuppered if our two original plans go down. The rule of three is a good approach to life in general. If we really need to get to a place it is good to have the location on our smart phone, but it is also good to have a map in our pocket and a number to ring as well.
Prepping is not really about shark attacks and zombies. It is a rational approach to life that irons out the bumps. A survivalist is a valuable member of the community who has thought ahead more than most. That is all.
