Quote for Thought
"We cannot afford to curtail soil conservation, either in the East or the West.  . . .  It is vital to the future of our farm areas, and though you may live in a city, what happens to the land of your country touches you as closely as if you were a farmer."  
Eleanor Roosevelt, My Day 3/6/1947
