For more than half a century, the Spud Drive-In has been a local landmark in Diggs, Idaho. Last month, with screenings of Despicable Me and Robin Hood, it became America?s first true digital drive-in. While other outdoor theatres have used digital projectors to show DVDs to large outdoor audiences, Spud is the only drive-in to date to actually employ digital cinema projection and surround sound audio. They plan to install 3D technology this month.
