In its July 3, 2006 Corrections, the Washington Post reports:
"In a June 28 Style review of "Superman Returns" (which was excerpted in the June 30 edition of Weekend), Superman's home state was incorrectly identified as Iowa. He is from Kansas."
It must be difficult for the Post's staff, even movie reviewers, not to be confused about flyover country, that great space between the coasts that they usually ignore.
