Bill Randall On A Shamus/Wizard Con In Cincinnati posted February 2, 2010
I saw your clip about the Seamus Heaney buying a Cincinnati comic-con. You underestimate the city's size: taken as a metro area, it sucks in 2.4 million people, making it the largest urban area in Ohio and 24th largest in the US. It's also within a five-hour drive from Chicago, Pittsburgh, Cleveland, Detroit. That Cincinnati hasn't had a major con has more to do with the city kind of sucking rather than being small.
That said, it has gotten better in the last few years.
