This poem I think sums it all up.
Empties Cuming Back
have you ever sat by the railroad track
and watched the emptys cuming back?
lumbering along with a groan and a
whine—
smoke strung out in a long gray line
belched from the panting injun’s stack
—just emptys cuming back.
i have—and to me the emptys seem
like dreams i sometimes dream—
of a girl—or munney—or maybe fame—
my dreams have all returned the same,
swinging along the homebound track
—just emptys cuming back.
-Angelo De Ponciano
