April 20

If you are a fan of the Charles Schulz comic Peanuts you might want to give some thought to throwing a party for Snoopy on the 20th because it was on that date in 1918 that the Red Baron (Manfred von Richthofen) shot down his final victims (the 79th and 80th). Richthofen would die of a gunshot wound the next day in an engagement with a Sopwith Camel piloted by Canadian pilot Wilfrid May. The fatal shot came from the ground however, not from his adversary.
