I assume if you wish to wander up the coast you will be taking US-17/GA-25 (Which keeps winding around over and under I-95)
I can only make a couple of suggestions,, As you come through DARIEN, GA if it happpens to be lunch time,, Billy's BBQ (Corner of US-17 and GA-251, directly across from Bi-Lo) best brisket I have ever had.
NOTE: if you want a beer with your lunch, he can not sell it. But Bi-Lo does, and the back side of the register reciept gets you half off on the 2nd dinner at Billy's. Lunch is about 8 bucks a pop.
Evening meal B&J's (A bit farther south, almost directly across from where I go to Church) will be on your left.
If it's late and you want a parking spot for the night.
Hang the left on 251, 4 miles to Cathead Creek, I'm on site 12
