Maybe not, but I can remember one particular blizzard 3 years ago, about this time of year, where 99% of the state of Montana was shut down for nearly 2 months, the MHP didn't even allow "emergency travel only", so if you had a medical condition, you were on your own. You couldn't get from point A to point B even in a 4WD vehicle, and snowplows in most areas gave up as they couldn't keep up with the intensity of snowfall, and many snowplow drivers had been working 18 hour shifts to begin with. It happend to hit right around Christmas time, and I was in Wisconsin, and wasn't sure I'd make it home.
BSF, some folks really have no idea what happens when you get frozen temps and a foot or two of snow. The drifting, the white out blowing conditions. The weight on the roofs that collapses home after home. That list goes on and on.
Great point about needing medical attention and being on your own because that is EXACTLY how it is. Same goes for foodstuffs also!
