In Confederates in the Attic, what characteristics of the South does Tony Horwitz find significant by the time he reaches Kentucky?Specifically...

By the time Horwitz reaches Kentucky, he has learned many
things about Southern character in general, and how Southerners remember the Civil War
specifically.  "Southerners are very strange about that war," Shelby Foote is quoted as
saying at the beginning of the book, and Horwitz has some stories to tell to prove it. 
At a library in North Carolina, Horwitz attends a birthday party for Robert E. Lee and
Stonewall Jackson where chicken-in-a-biscuit and lemon snaps are served to honor,
respectively, Lee (and the pet hen he took with him during the 1863 campaigns) and
Jackson (who was said to have sucked on the candy during fighting).  In South Carolina,
Horwitz learns that Charlestonians would just as soon forget about the war and focus on
tourism, and in Columbia, he meets a gentleman who decrees that the United States
government is being controlled by Israel and the only hope for America is to revive the
Old Confederacy.  In Kentucky, Horwitz stumbles into a near brawl at a dangerous biker
bar called "Redbone" and then finds Jim and Velma recruiting for the KKK out of an old
rusty Buick. While Jim proselytizes abou "God, Race and Nations" and collects $25 from
anyone wishing to join, Velma regales Horowitz with stories of her grandkids, Christmas
crafts, and a cross-burning she is looking forward to.  In Virginia, he takes part
in the Confederate side of a reenactment of the Battle of the Wilderness, and later
receives withering looks from African-Americans in the grocery
store.
