Sounds like you are close to the Natchez Trace. Not sure why you would ride TN-840 and I-40 unless you were in a hurry to get somewhere. A lot of great roads when you stay away from Nashville.
Head over to Leiper Fork. You might even run into Mike Wolfe.
I certainly hear ya twowheel.
The plan wasn't to ride 840, but I did want to get over to Jackson along I-40 and then cut north to Paducah and come down the middle of LBL. The THP designated crime scene on I-40W brought it to a parking lot. Had to adjust the plans from that point. Since my G4 headset fubar'd in my helmet while I was suited-up and ready to go, I had to deal with that. Oh, and that was right after my heated jacket liner harness decided it wanted to just undo itself as I was putting it on. Both made me miss my departure time.
Then, from Ashland CIty to Charnotte on TN-49, some joker wanted to do 15mph
under the posted limit on double-line pavement, and not willing to let collecting traffic pass!
Then, the I-40 stop. Too many things indicating to just go home. That's when I said, nope! Just keep it simple, now. Everyone has had those days, right?
Been on the Natchez Trace too many times now. This photo is from a few weeks ago. Must have been getting a little silly at the moment. I've been passed by a pick-up truck and a Prius since I don't push anything on that road.
