Famous quotes containing the word rain:

    He had the oaks for heating and for light.
    He had a hen, he had a pig in sight.
    He had a well, he had the rain to catch.
    He had a ten-by-twenty garden patch.
    Nor did he lack for common entertainment.
    That I assume was what our passing train meant.
    Robert Frost (1874–1963)
