The question I like to ask preppers is "what, exactly, are you prepping for?". There's a right and wrong answer to that question. In the military, we called it the "postulated threat", the most likely thing that could happen to you that we would call "bad". Then, you design your training, weapons, equipment, and procedures around that threat. Sure, while a zombie apocalypse or alien invasion would be pretty bad, it's also not very likely, so why prep for that event? A snowstorm in Nebraska, however, is very likely (at least it used to be), and could leave you isolated for an extended period of time. Do you have enough food, water, power, provisions, etc. to survive until things get back to "normal"? Are things prioritized? How do you communicate with/get information from the outside world?
