I've got the fridge all stocked up - or nearly so - just waiting for the snow to hit the Vineyard...
Now that I dont have to plow the airport out - I actually enjoy it again !
Fridge?
What you really need to wait out a snowstorm is some jugs of drinking water, canned food with a good expiration date (and a manual can opener... duh), a bunch of blankets, and something to burn. A couple of bags of charcoal will work, but some people keep a stockpile of camping gear like propane, propane stoves, or even cans of sterno. A box or two of candles is also a good thing to have. For peace of mind and to be able to hear announcements about shelters, food and medical supply handouts, power outage details, etc., you need an emergency radio with plenty of spare batteries.
If you rely on the house electricity or gas supply to make it through a bad storm, you're begging for life threatening trouble. The worst story about a storm I ever heard was about 15 years ago... Some old lady tried to wait out a storm, and didn't hear the evacuation order when the power company said it would take a week to fix the power lines. After about day 3 of sub-zero temps, the pipes burst in her kitchen, and the water started to freeze. She fell after slipping on the ice in the kitchen and broke her hip so she couldn't get up, but the water from the broken pipe kept coming in for another day. When rescuers found her another couple of days later she was frozen to the floor lying down embedded in about 3 inches of ice, but she was still alive because of severe hypothermia that shut down everything but her heart and lungs. She lived, but was pretty messed up of course.
