If you're heading south on 49 for the Swap Meet...

... Be aware of a slight detour around downtown. I'm pretty sure this will happen just after Tuttletown, and will direct you onto Rawhide rd, which is an awesome stretch of freshly paved curves and hills, that will dump you onto highway 108, in Jamestown. 

From there head past Sonora on 108 and follow the signs from the highway. 

As long as the cops don't rip them down!
