Outdoor-sign companies are salivating over the end of a 34-year-old ban on billboards along the state's highways. We're betting last week's ruling by the Oregon Supreme Court will prompt Clear Channel to spring into action with beautifying half-acre placards for outlet stores and smooth-jazz radio stations.
