I will add that Mason, about halfway between Cincinnati and Dayton, is pretty ideal for hearing both of those markets at local strength. I had a work trip down there Thursday and Friday and was reminded that, outside commercial breaks that always seem to overlap, there are plenty of quality choices on very listenable signals.
I was amused that the Bengals game was on four powerful signals in that area in WLW, WEBN and WCKY from Cincinnati and WTUE from Dayton. WCKY was the weakest of the four signals and even it was very listenable at all hours, more than I expected given that I've heard cancellation on 1530 that close in.
An aside, Dayton AMs pretty much disappear in Mason at night, only 25 miles or so south of their towers. Even as early as 7:15 when I was driving back from dinner, WHIO and WING were gone. WONE was there but really weak.
