Yes, America....there really is a Hidden Valley Ranch! In 1954, Steve and Gayle Henson opened a dude ranch near Santa Barbara, California called Hidden Valley Ranch. To their guests, they served a dressing that Steve had developed. The dressing was popular, and they began selling bottles that guests could take home. This expanded into mass production which continues today but no longer with the Hensons. The secret formula is now owned by the people at Clorox Corp.
