Famous quotes containing the word country:
“Here in the country it is only a few idle boys or loafers that go a-fishing on a rainy day; but there it appeared as if every able-bodied man and helpful boy in the Bay had gone out on a pleasure excursion in their yachts, and all would at last land and have a chowder on the Cape.”
—Henry David Thoreau (1817–1862)
“The citizen who criticizes his country is paying it an implied tribute.”
—J. William Fulbright (1905–1995)
