I'm in Lexington, KY. It's a 1.5 hour drive to CVG and Louisville as well.
I frequent IAH and Harrisburg, PA when I travel. I'm possibly getting engaged soon and might be looking to go somewhere international for our honeymoon later in the year (if all works out).
I just applied for a US Airways card - 40k miles on first purchase, 10k at year 1 anniversary, 2x $99 companion vouchers. Looked like one of the better deals right now.
