Posting Visiting AD for Columbia /Jefferson City Mo...

Hello,
. I am a VP in KC,MO and travel some have been asked to come to Columbia,Mo by a few of my clients who come visit me in KC & Springfield,Mo I am wondering if I post there what city is best to put my ad under? KC , STL, or Springfield?

The STL forum covers both Columbia & Jefferson City ...so the Ad would be good here.

THANKS SO MUCH ... thought that it did wanted to make sure...
