What are the circumstances in which Sylder once again encounters the old man?

Sylder is doing a whiskey pickup when he is startled by shotgun blasts. He ducks and hides for a moment, but discovers that they are coming from an old man, the orchard keeper, shooting a large "x" in the side of a government tank that is on his property. His operation is methodically: He slowly loads the shotgun shells, discharges them, opens the shotgun, examines the spent shells, discards them, and repeats it again. Sylder gets the rest of his whiskey, and as he is ready to leave he sees the old man standing on a hill, shotgun still in hand, watching him. He ducks his head and speeds away.
