As part of the state's Centennial Celebration in 1989, the Washington State Department of Agriculture sponsored a program recognizing farms that had been in the same family for 100 years of more as centennial farms ... this brochure features three of the hundreds of centennial farms still farming today.

The Centennial Farm Recognition Program was a one-time effort conducted by the Washington State Department of Agriculture as a part of the state's Centennial celebration. This addendum includes profiles of 21 farms, identified in 1989, that met the criteria but did not meet the Washington Centennial Farm project deadline. Since the applications were received late, the Agency requested a revised application and would include the information in the Project's permanent records, although not in the Centennial Farm Book. With the 2014 project to reconnect with the original centennial farms, these additional farms were included as a separate addendum. The addendum farm information is current to 1989.

Washington was rarely isolated from the world during his eventful life. His diary for 1751-52 relates a voyage to Barbados when he was nineteen. The next two accounts concern the early phases of the French and Indian War, in which Washington commanded a Virginia regiment. By the 1760s when Washington's diaries resume, he considered himself retired from public life, but George III was on the British throne and in the American colonies the process of unrest was beginning that would ultimately place Washington in command of a revolutionary army. Even as he traveled to Philadelphia in 1787 to chair the Constitutional Convention, however, and later as president, Washington's first love remained his plantation, Mount Vernon. In his diary, he religiously recorded the changing methods of farming he employed there and the pleasures of riding and hunting. Rich in material from this private sphere, The Diaries of George Washington offer historians and anyone interested in Washington a closer view of the first president in this bicentennial year of his death.
