Last weekend I drove through the Skokie Lagoons, just north of Chicago. They are both beautiful and manmade, created literally from the sweat of the Great Depression. Four million cubic tons of soil were removed to form a series of lagoons from the existing marshlands. It was one of the largest public works projects of FDR's Civilian Conservation Corps, employing thousands of men, including three African-American construction companies. Started in 1933, the project took until the beginning of the US entry into World War II in 1941 to complete.
