The route is easy to find and follow. Just start in Milan, TN and travels SE to Saltillo, TN on Hwy 104 (follow the signs).
You will start your ride through the Milan Arsenal, which is a US ammunition facility. You'll be traveling through thick wooded areas and not far from the Natchez Trace State Forest and Resort Park (about 8 miles off the route). Also, you can stop by Parkers crossroads and see lots of Civil War sites.
Start in Milan, TN and follow SR104 to Saltillo, TN. Road condition is good. There are plenty of twisties and some nice hills. This is probably one of, if not the best rides in West TN. Deer are plentiful so watch the roadside.
Gas and drinks are not a problem but not much else out there (unless you head over to the Natchez Trace state park areas).
