Town Hall, Herndon Dairy; The Scott family, Caitlin Dearing, Alistar, 2½, and Cameron check out one of the newest Herndon Historic Markers, this one located on the Town Hall near the Herndon Depot. In the early 1900s Herndon dairy farmers led the state in production. For decades, dairy farming was the primary industry and dominant land use of Herndon. Herndon downtown businesses flourished in support of the industry. The railroad provided a fast way to move fresh milk to markets in Washington, D.C. From a platform previously located on this site, farmers loaded their milk containers onto the train each morning and returned each evening to retrieve their empty containers for reuse the next day.
