CINCINNATI (AP) — Officials with Belterra Park Gaming in eastern Cincinnati say they're disappointed with the new racino's revenues, which accounted for the smallest slice of Ohio's $1.5 billion gambling market in the past year. The Cincinnati Enquirer reports (http://cin.ci/1Hcxyjr ) the race track and casino facility has averaged $4.6 million in revenues each month, but officials hoped those figures would reach at least $7.5 million.
