Route 76.. if that is the road I think it is then I've driven part of that route (I call the part of 76 I drive the sequential numbered highway. It has 2 or 3 numeric designations one of shich is 123)
The georgia part is foothills.. Not serious mountain driving, it is a bit stressful but not really a problem.. I enjoyed that part.
When you get to Seneca SC if you want to stop (Traveler's rest is a bit out of the way) there is a lovely County park,, South cove
Directions from 123/76 follow
Watch for the big plazas.. Applewood and Bi-Lo on the right,, Just past the Bi-Lo plaza is 28 (to the left) and something else to the right.
Turn left 2 lights turn right, turn right at the first road to the right (about a quarter mile) (South Cove Road) Park is at the end of the road.
Most of the sites are easy in / out and a mix of 30/50 amp.. One dump station.. IF there are a couple of camp hosts (Fred and Betty) parked there in a big class A.. Say hi to 'em for me (They are the older camp host couple) 0.
Home is where I park it!
