HIGH POINT, N.C. -- Every time it snows hoards of shoppers flood the grocery store looking for two things: bread and milk.

If you head to the grocery store today, it might be difficult to find these two foods that have become synonymous with snow.

But, why do we gravitate to bread and milk?

Well according to accuweather.com New England is to thank for this tradition.

One theory is that the blizzard of 1978 left people trapped in their homes for weeks.

In November a writer in Pittsburgh did some research on one of the worst snowstorms to hit the city in 1950 and found the city got almost 3 feet of snow in just two days.

After looking back through some newspaper articles, she found the city had a bread and milk shortage at the same time.

So, naturally, anytime it snowed after that, everyone rushed to the store.
