I've heard the same things as fiberpost mentioned above. Knew a lot of people who lived in KY and worked in Cinci...not too many the other way around.
Of course that makes traffic to Cincinnati fairly bad, at least compared to where I live, but not bad compared to Ft Worth, I imagine. I also feel like the I-75 bridge across the Ohio is so old and rusty that it's going to collapse.
Also, the airport's in Northern KY. FWIW. See you at the BYU Cincy game next year.
