I live in West Virginia. As far back as I can remember, we always prepped for winter, although we used to call it "stocking up". We didn't go all out, but made sure we had enough no matter what the winter might bring. Some of our worst winter situations were:
Being stuck in the house for 19 days straight.
Losing electric (and heat) during Hurricane Sandy and us being hit with a blizzard.
Losing power (and heat) when the wind chill was sixty below zero.
Water pipes froze and we had no water for almost 2 weeks.
Even in the best case scenario, I don't like dragging a bunch of groceries in the house when it's cold, snowing, and icy, so I always do some prepping for winter.
