Muscle Shoals. The name alone is great. It sounds like it should be a blues song or a dive bar or both. Turns out it's a small town of about 15,000 people in the far northwest corner of Alabama, sitting on the Tennessee River, and it's home to one of the more remote stops on the RTJ Trail. Getting here takes commitment. It's over an hour from Huntsville, about two and a half from Birmingham, and there is not a lot happening in between.
