"ASIMOV WAS A BIGOT.” The graffiti, sprayed across the bucket of a Soviet ore hopper car, one of a long train of them. Then a slash of Cyrillic, the same message probably, obscured by a crust of snow and mud and grit. Not clear from the lettering if it was a human hand that wrote it."
Quasar links out; the story lives on Asimov's, where the author gets the click.
