Indeed. There are people who like to maintain that Steinbeck wasn't a "real" writer, and that "Grapes of Wrath" proves it. They are, of course, wrong.
I'm putting a LOT aside by only objecting to the exclusion of "The Grapes of Wrath," in preference to "The Sot Weed Factor". There are many others that I would include in the running, but this exclusion is straight out wrong. It is, however, somewhat "heartening" to see that they have some sense of the erro´rs of their ways. FWIW.
