Yes, Shake Rag Rd has a street sign, there is corner store/gas station at the intersection. Just follow that all the way up. When you get close to the top it will get severely rutted out. The stock TJ for sure will want to take one of the bypasses.
For Day 2 if Beasley is not open then maybe do Charlies Creek and Flatlands.
Charlies Creek is off of Upper Hightower Rd in Hiawassee about a 30 min drive from Bell. You take route 2/76 east to Upper Hightower then turn right on Charlies Creek. There are some fun off shoots. You will eventually end up on Sandy Bottom and then Tallulah River Rd. At the end it will look like the road dead ends at the river. You just cant see where it pics up on the other side. When the road ends drive into the river allong the right side for a couple hundred feet and then you will see the road starting up on the left. It shouldn't be too deep if it doesn't rain too much this week.
I have never been to Flatlands myself just heard it's a fun place to go. Check out
Flatlands (Georgia) | JeepsonTrails.com
for the coordinates at either end. Maybe someone else can chime in here about it too.
