Famous quotes containing the words south and/or bay:
“To lib and die in Dixie!
Away, away, away down South in Dixie!”
—Daniel Decatur Emmett (1815–1904)
“Three miles long and two streets wide, the town curls around the bay ... a gaudy run with Mediterranean splashes of color, crowded steep-pitched roofs, fishing piers and fishing boats whose stench of mackerel and gasoline is as aphrodisiac to the sensuous nose as the clean bar-whisky smell of a nightclub where call girls congregate.”
—Norman Mailer (b. 1923)
