WHERE IS ODYSSEY IN ADVENTURES IN ODYSSEY?

Adventures in Odyssey is a radio show that's been on the air since the 80's, however, the stories are timeless. There are a couple of sites devoted to it: www.aiohq.com and www.whitsend.org. Anyhow, as I listen to the episodes I sometimes wonder where Odyssey could theoretically be located. I've decided to start compiling a list of different things that may help us to locate the mysterious town. If you have anything extra to add, please comment on them and I'll add them to the list.

1. In Episode 2, "The Life of the Party", Craig Moorhead's parents get into a fight and the Dad threatens to pack up the car and move back to Columbus. This would lead us to believe that the Odyssey is within a day or so drive of Columbus. There is a Columbus in Arkansas, Georgia, Indiana, Kansas, Kentucky, Michigan, Mississippi, Montana, North Carolina, North Dakota, Nebraska, New Jersey, New Mexico, Ohio, Pennsylvania, Texas, and Wisconsin. This means that Odyssey could still be anywhere.
2. The radio station that is broadcast from Whit's End has the call letters KYDS. I believe all radio stations that start with K are all west of the Mississippi River. That cuts out all states East of the Mississippi River.
3. Mysteriously, even though the call letters would lead you to believe Odyssey is West of the Mississippi River, in The Underground Railroad, they cross the Ohio river in order to make it to what is now Whit's End. This would point to Odyssey being in Ohio.
