Why was the Sonoma County Fair founded?

The Sonoma County Fair was primarily founded as a platform to highlight and promote the region's agricultural resources, showcasing the local farming community's achievements and products. While it does feature various activities beyond agriculture, such as entertainment and arts, its roots are deeply embedded in celebrating agricultural accomplishments and providing a venue for local farmers to display their livestock and crops.

The fair serves as a community gathering point that emphasizes the importance of agriculture in the local economy and culture. Thus, selecting the answer focused on creating a race track and expo center overlooks the fair's fundamental purpose related to agriculture and community engagement. The primary mission reflects the historical and ongoing significance of agricultural exhibits, competitions, and educational opportunities surrounding farming practices and livestock showcasing in Sonoma County.
