I am going to tell you a true story. I used to live in the Eastern Sierra's in a town called Bishop. We lived 9 miles outside town and 3 miles up a mountain in a very isolated area outside of the city limits.
The day before Thanksgiving it started snowing - nothing unusual, we worked our day and drove home in the snow. Later than night it became a complete white out. You could not see your hand in front of your face. We all went to bed thinking that, as usual, it would stop, we could shovel out and our guests would come for a good dinner.
In the morning, not only was it still snowing, it was already 5 feet high around us. Doors couldn't be opened, cars couldn't get out, people were stuck. We had a small community of about 49 houses. I had a turkey and stuffing and potatoes, but nothing else. I had planned on going to the store that day.
Pretty soon, here comes my neighbor wading through the snow to see if I had any butter. I had butter and asked her if she had any veggies she could spare. Another neighbor came over and asked if we had any chicken stock, yes we did, and I asked her if she had any dessert she could spare. And she did. Next thing we knew, we were all at our house with the biggest thanksgiving feast you can imagine. I had never had such variety of food or cultures in my life. It was the best holiday I can remember and I would love that to happen again in any case of emergency.
