Does the Nashville terminal have driver showers? And if so, where?

To answer my own question: Yes, in the drivers lounge inside the shop. Go in the man door closest to the guard shack, drivers lounge is ckearly posted. Showers are first door on the left. Laundry is the second door. The women's shower is second door on the left just as you enter the shop, next to the nonworking drinking fountain. There is only one.

Yes.
