Famous quotes containing the word road:

    Dear common flower, that grow’st beside the way,
    Fringing the dusty road with harmless gold,
    First pledge of blithesome May,
    Which children pluck, and, full of pride, uphold,
    Hight-hearted buccaneers, o’erjoyed that they
    An Eldorado in the grass have found,
    Which not the rich earth’s ample round
    May match in wealth—thou art more dear to me
    Than all the prouder summer-blooms may be.
    James Russell Lowell (1819–1891)
