Famous quotes containing the words south and/or bay:
“Up from the South at break of day,
Bringing to Winchester fresh dismay,
The affrighted air with a shudder bore,
Like a herald in haste, to the chieftain’s door,
The terrible grumble, and rumble, and roar,
Telling the battle was on once more,
And Sheridan twenty miles away.”
—Thomas Buchanan Read (1822–1872)
“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)
