Memphis to just outside Nashville

I decided to get off the freeway today and told the Satnav to avoid them, it took me northwards up though the sticks of Arkansas, the land is flat and mostly fields however every so often there are small copses of fields with farmsteads in them. I had a litle twinge of pain in my back so as I speed through a small village I pulled in to a Chemist for some Paracetamol. Opposite was a restaurant called Piggy P's, as it was already lunchtime I called in for some typical Southern grub of Pork and fries and Iced Tea. I continued on up the small road and suddenly the road doglegged to the right and left and under a strange archway over the road. I didn't realise it but I'd actually travelled up to into Missouri. I didn't get chance to stop at the weird arch, I had a huge truck right up behind me pushing me along and eventually I got a straight bit of road and allowed him to pass. I came across a radio communications store and pulled in to see if I could get a new battery for my radio they didn't sell Yeasu kit but they did give me the name of a store that may over the river in Dyersburg in Tennessee. I drove about another 20 miles up to the bridge over the Mississippi and headed into Dyersburg. I only had the name of the company and wasn't sure how I would find the firm. As I got into the down town area I came across a Library so I pulled into the carpark and used the internet there to track down the company. I got an address for them but my Sat Nav showed it as being about 10miles out of the town. As it was in the general direction of Nashville I headed out there. Unfortunately there was nothing but fields when I got to the 'address'. Rather than go back into Dyersberg I carried on towards Nashville but ended up stopping at a Motel about an hour out as I was too tired to drive any further and my back was still playing up. Across the road from the Motel was the Lorretta Lyne Restaurant and Gift Shoppe, apparently she's a world famous County Star – sorry never heard of her; however the all -you-can-eat buffet was good at only $9 a pop.
