Let me add, if you're in an area that could survive, it is wise to try & be as prepared as you could be. Being just due west, not far from Wash DC & right down the road from Dover AFB, my place would be snuffed out in a nanosecond.
Nuclear fallout is one thing, but not many are talking about what a serious, massive solar flare or CME could do, & the Sun is a very active place, no one has to push any button, it happens, we just haven't been in the direct pathway of a colossal event...yet.
