The Cincinnati graticule is at latitude 39, longitude -84. It includes the Greater Cincinnati and Northern Kentucky Metropolitan areas as well as most of the Dayton, OH Metropolitan Area and the schools University of Cincinnati, Xavier University, Thomas More College, College of Mt. St. Joseph, Cincinnati State, University of Dayton, Wright State University, and Sinclair Community College. Although it is almost entirely land, the Ohio River and numerous tributaries as well as the Wright-Patterson Air Force Base are also located here, possibly limiting the number of available geohashes.
