Famous quotes containing the words open, game and/or license:

    The secret point of money and power in America is neither the things that money can buy nor power for power’s sake ... but absolute personal freedom, mobility, privacy. It is the instinct which drove America to the Pacific, all through the nineteenth century, the desire to be able to find a restaurant open in case you want a sandwich, to be a free agent, live by one’s own rules.
    Joan Didion (b. 1934)

    The savage soul of game is up at once—
    The pack full-opening various, the shrill horn
    Resounded from the hills, the neighing steed
    Wild for the chase, and the loud hunter’s shout—
    O’er a weak, harmless, flying creature, all
    Mixed in mad tumult and discordant joy.
    James Thomson (1700–1748)

    All is possible,
    Who so list believe;
    Trust therefore first, and after preve,
    As men wed ladies by license and leave,
    All is possible.
    Sir Thomas Wyatt (1503?–1542)
