I live in NC around 10 minutes from the SC state line. Once or twice a month I drive down to a little gas station that has a Krystal attached. I get my gas for 30 cents less a gallon than in NC and then move onto Krystal where I get the 4 krystals, a fry and a coke combo meal
I believe that's the last Krystal restaurant headed North on I-85 so I'm glad it's near me at least. When I lived in Florida there was tons of them.
