Well, we have had similar storms here in Eastern PA - they don't come often, but they DO come.

In the storm that socked Boston so hard (which was not as bad here), we lost power for a day, which necessitated the use of a generator to operate our water well and septic system.

I'd say that we could run "autonomously" here at the house for about 10 days, that's assuming we manage generator use and water consuption, and of course, we need to maintain a decent stash of firewood, because we try to heat our home with wood as often as possible in the winter. This year, unfortunately, we've raced through our firewood stores, and I have at most 2 weeks wood left. I always like to end each burn season with about 2 weeks worth of wood left, this year, I'll actually run out of wood before winter runs out.

As far as food and stuff - again we have supplies in the pantry for quite a while.

Just FYI - for BIG storms like this, the snowplow guys (and I know several of them) get called in durring the early phases of the storm and they don't get to go home.
