From Geo Hashing
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, Ohio Metropolitan Area and the schools University of Cincinnati, Xavier University, Miami University, Thomas More College, College of Mt. St. Joseph, Cincinnati State, University of Dayton, Wright State University, Earlham College and Sinclair Community College. Although it is almost entirely golf courses 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.

Just East of the Dayton Airport. Looks like a good spot.
