Driving across the country with my son (great fun), in Arizona the bright sun was blotted out with a red cloud. Dust.
The person at the Agricultural inspection station at the California boarder said it happened every so often. It is just from the desert not the agricultural land. But I dont know… wild.
I recently read a wonderful book about the economic and political circumstances of the Dust Bowl in the 1930’s– it is the same overstomping application of capitalism that got the country into the stock problem. I do not think much has changed since then, and we had some recurrance last year of dust storms.
