Katie the Cow started out in front of a local company called Kinnett Dairies (KD, hence the name). They bottled milk, made ice cream, etc... when she was put up 55-60 years ago, it was out past the edge of town on GA Highway 85 and was a landmark showing that you were almost in Columbus.
Fast forward a few decades and Kinnett Dairies is in the middle of town and right beside the then new mall and the local airport right at an interstate exit. Kinnett went out of business, the building was torn down and retail spaces built but the plan to do away with the cow was met with local resistance, so Katie stayed where she was in the new Best Buy's parking lot- to the confusion of countless visitors to the town.
For a while, she was joined by a mysterious calf statue that was about 6 feet tall which just appeared on night. When it was stolen a few years later, the rumors of lynch mobs and vigilence committees made the calf reappear behind the dumpster at a McDonalds in short order.
Recently, retail has moved further out and there's been vandalism on Katie, so she was moved downtown.
