The Dust Bowl, also known as the Dirty Thirties, was a period of severe dust storms that greatly damaged the ecology and agriculture of the American and Canadian prairies during the 1930s.

Do you turn your glassware upside down in the cupboard? If your family tree has roots in the prairies of the 1930s it could be a habit left over from previous generations and their experiences with the Dust Bowl. This habit got passed down to me.
