Oh, mighty Cesar, beware the Ides of March. In 44 B.C. Julius Cesar is murdered on the floor of the Roman Senate by his loyal servant Brutus.

461 A.D. Saint Patrick dies at Saul, Downpatrick, Ireland. He is believed to have used the three leafed clover in art to describe the Holy Trinity. For thousands of years the Irish have celebrated the day of Saint Patrick's death as Saint Patrick's Day.

I wonder if either of these men were fly fishermen or if fly fishing even existed back then?

Oh well, Happy Saint Patrick's Day everyone.
