Gyms in TN

My parents live in the Spring Hill TN area and I have wanted to climb at a gym while visiting, but I don’t really want to drive all the way to Franklin/Nashville. Is there a reason there isn’t a gym in the Columbia/Spring Hill area? I feel like there is a ton of potential for gym in that area. 

Climb Nashville has a location in Murfreesboro now, but that looks more or less equidistant to Spring Hill from Nashville. 

Climb Nashville West.
Climb Nashville East.
Climb Nashville Murfreesboro. 
The Crag Franklin.
The Crag Nashville.

Those are the only options I know of near Spring Hill
