This week on Columbia Business One-on-One we talk with Nickie Davis, the executive director of the Downtown Community Improvement District.  It's Wellness Weekend in the District so we give a run down of all the activities plus talk about an active Fall for the folks in downtown Columbia.  We then have a conversation with Abbie McNair, the general manger of the new Riddle's Jewelry store in the Columbia Mall.  Abbie tells us about the history of Riddle's family owned stores and the details of how they chose Columbia as there first entry into the state of Missouri.  Finally, we replay a conversation from the Morning Meeting with Simon Rose on NewsTalk 98.9 FM/1400 AM KFRU with Mike Schupp of MODOT about the demolition of the Rocheport bridge this Sunday morning.  Lots of final details in their conversation.
