Steve's barking at the double depression of the 20s and 30s

I seem to recall reading about a double depression in the United States during the 20s and 30s.
The first was the collapse of farm prices during the 20s forcing many a farmer to lose their farms.
This was called the rural depression. This was followed by the urban depression starting with the collapse of the stock market. Of cause the rural depression continued. I guess you can't call a depression a depression unless it meets a snobbish definition of one, so the rural depression doesn't count.
