Famous quotes containing the words national and/or trail:
“What do we mean by patriotism in the context of our times? I venture to suggest that what we mean is a sense of national responsibility ... a patriotism which is not short, frenzied outbursts of emotion, but the tranquil and steady dedication of a lifetime.”
—Adlai Stevenson (1900–1965)
“You will trail across the rocks
and wash them with your salt,
you will curl between sand-hills
you will thunder along the cliff
break retreat get fresh strength
gather and pour weight upon the beach.”
—Hilda Doolittle (1886–1961)
