Flappers, bootleggers and booze — the decade following WWI was popularly known as the "Roaring Twenties."

In Sonoma County, residents were keeping pace with the rest of the nation. Women's hemlines were shorter and hair was bobbed. Following a suffrage movement, women gained the right to vote in the United States in 1920, but California residents had the privilege since 1911.

By 1927, Sonoma County was several years into Prohibition. Hop growers endured by selling crops to European brewers. Fetter's Hot Springs visitors could soak in the actual "hot waters" or partake in the alcoholic kind.

The major source of income for county residents was largely agricultural. Dairy and eggs were big business in Petaluma, where Lyman Byce's 1879 invention of an egg incubator turned the city in the "Egg Basket of the World."
