Famous quotes containing the word fields:

    I will never accept that I got a free ride. It wasn’t free at all. My ancestors were brought here against their will. They were made to work and help build the country. I worked in the cotton fields from the age of seven. I worked in the laundry for twenty- three years. I worked for the national organization for nine years. I just retired from city government after twelve-and-a- half years.
    Johnnie Tillmon (b. 1926)
