"We are hopeful that we can create the best outcome for the New Orleans community, Fair Grounds' creditors, Louisiana horsemen, the racetrack's workers and customers, and out shareholders.Fair Grounds identified CDI as a stalking horse in an amended Chapter 11 reorganization plan filed June 25. An original plan filed in April did not specify an opening bid from any group.If the proposed auction is approved, it could be completed as early as Aug. 16.
