I do remember when Greyhound had a route from Columbia to Louisville. My dad, Clifton Walker, drove a Greyhound bus from 1981 to 1987. He called the route from Columbia to Louisville the "Columbia Run". He drove that route part time, when the full-time driver, Joe Banks, I believe from Columbia, was either off work or driving another route. The route started in Columbia, then to Greensburg, Campbellsville, Lebanon, Springfield, Bardstown, Fern Creek, then finally to the bus station in Louisville.The Columbia Run ended I believe in 1986 because not enough people were using the route. -John Walker
