If You Knew You would Die Tomorrow

Jogging through the grand and sprawling Oakwood Cemetery, on the National Register of Historic Places, Uncle Sam is buried here.... reading the names and Born/Died dates on the headstones, grateful to be alive on this sweet summer day I wondered.... if you knew you would die tomorrow, how would you spend today?  Is there one more thing you would say?  One more thing you would do?  What would you want written on your grave marker?  Surely something more than dates.
