Dayton should make it into Cincinnati every day. Indianapolis is a little farther out, but not entirely out of the possibility of daily reception depending on open frequencies. Now on the other hand, if a class A (6kw or less) or lower (translators and LPFM's) from Indianapolis or Louisville made it into Cincinnati then it would be worth noting.
In Coldwater, MI, I can count on daily reception from Detroit (100 miles) and Chicago (135 miles). I can also get WGNR and WIBC from Indianapolis on a daily basis. This is just with a $25 6-bay antenna.
I'm probably a youngster (26) compared to most DX'ers here, but i've been into DX'ing since I was in HS. I never logged my catches until '02. Six years and 1130 stations later, i'm still looking for new logs. It's good to see people still discovering the hobby. As you go along you'll discover more, farther away stations beyond Indy, Cincy or Louisville. Find an open frequency and if conditions are favorable, you'll hear stations from possibly 200 miles away.
Good DX'ing!
