QT ... only one I've heard about is the one on the corner of Holmes Bend Rd & 1580 ... and slabeye (Rodney) told me about getting work done there on his motor. It's right across the road from The Getaway (t.slabseeker's rental cabin), if you know where that is.
There are several places around the Campbellsville area, but never had anyone mention them as their "go to" place. Hopefully, some of the other locals will chime in and give you theirs.
