Wartime blackout restrictions, designed to keep outdoor lighting at low levels, caused another problem for baseball. These rules limited traveling and night games to the point that the 1942 season nearly had to be canceled. On January 14, 1942, MLB Commissioner Kenesaw Mountain Landis wrote a letter to U.S. President Franklin D. Roosevelt and pleaded for the continuation of baseball during the war in hopes for a start of a new major league season. President Roosevelt responded, "I honestly feel that it would be best for the country to keep baseball going. There will be fewer people unemployed and everybody will work longer hours and harder than ever before. And that means that they ought to have a chance for recreation and for taking their minds off their work even more than before."
