Cincinatti has the real Kentucky across the river. I wonder what that's like. (The reverse could be said as well, and I haven't been to Cincinatti but I'd like to go some day, partly because I saw the Kaufman movie Anomalisa which is set there, and I made a point to check out Schenectady from another Kaufman movie and I was glad I did.)
I was lucky enough to be the only person who showed up for my tour slot, so the guide and I had a lot of time to talk about the art deco, the history, etc.
Oddly enough, the Kentucky side of Cincinnati is nicer than the OH side, at least near the river.
It's worth checking out, but I found downtown Cinci weird. It was completely lifeless at night. Haven't been in 15 years or so, so it's entirely possible that's changed now. Other than that, it's a neat area. Make sure to checkout Jungle Jim's, it's a unique enough store worth a visit.
