ARMY NAVY GAME
On December 2, 1961, President Kennedy attended the Army-Navy football game in Philadelphia.
President Theodore Roosevelt attended the Army-Navy game in 1901 & was the first President to cross the field during halftime. The tradition has continued since. (JFK is carrying on this tradition in the photograph above.)
A President will sit on the home side during the first half & then on the visiting side during the second. One action of TR, however, did not become a tradition. He became so excited after a Navy TD, he ran to the sideline slapping players on the back.
