Speaking of pedantry, Catspaw, you're right about the route of Hwy 61 going from Memphis to New Orleans, but mistaken about Hwy 51. It doesn't go through Jackson or the center of the state. Instead, it parallels the Miss River about 20 miles east of it from Memphis to Union City near the Kentucky border. You're right about there having been a few klansman along there (Night Riders), though. Both highways provide good songwriting material.
