If you go Hwy 85 North to exit 1 in South Carolina and take a left at the top of the off ramp (onto Hwy 11) and drive about 16 miles, you'll come to Hwy 123. Take a right off of Hwy 11 onto ramp to Hwy 123. At the stop sign, make a left and travel about 5 miles down Hwy 123 and you'll see a Wal*Mart on the left. In the parking lot in front of WM, you'll see the Jack-N-Tha-Box. This will be Seneca, SC. This is the closest one. It is about 20-30 minutes after you get off the interstate.
The one David is talking about is up I-85N to exit 51 (Woodruff Rd.) Get off at Exit 51 and make a left and it will be about a block or so down on the left. This one is about forty-five minutes into South Carolina.
Later, QD.
