Kevin Costner has been chosen to be the honorary chair of Moonlight at the Ranch IV: ‘The Roaring 20’s!’ “It adds just the right ‘touch of class’ to make this another ‘untouchable’ great event,” said Santa Paula Police Chief Stephen MacKinnon, chairman of the Moonlight IV celebration. Moonlight at the Ranch, Ventura County’s signature event, will again benefit the Santa Paula Police & Fire Foundation and Chamber of Commerce. “Even though Kevin’s busy schedule can’t confirm his possible attendance just yet, he is already known as a strong supporter for Public Safety” and, noted MacKinnon, “we’re thrilled with his involvement.” The event will be Saturday, September 18, 2010, from 5:30pm to 11pm at historic Limoneira Ranch, a venue constructed in that era of excess. “The password is ‘Joe sent me!’” and tickets are only $60 each. There’s a picture of Kevin as Elliot Ness in ‘The Untouchables’ with the article.
