Cardwell notes that they were in Paris, KY on December 31. (pg 31 Cardwell) as does Touring with Cable and Huck, Scharnhorst has them in Hamilton:

December 31 Wednesday – George Cable wrote from Dayton, Ohio to his wife Lucy:

“I told you in last night’s letter that we had a good time in Pittsburgh; & so we did. Not the best sort, however. We pleased our audience thoroughly & it was a large & cultivated audience. The newspapers, however, must have taken some grudge against us; for they made offensive reports of the affair” [Turner, MT & GWC 77].
