A pond that was dry during last year's drought is full again near Sprague, Neb., on Thursday, April 25, 2013. Farmers who have spent the past several months staring at parched fields have a new problem: mud. A rainy spring has brought weeks of rains to the middle of the country, and while it hasn't completely ended the historic drought, new forecasts show it surely has helped. (AP Photo/Nati Harnik)
