Fairly standard gas station stop here, but super busy since it is on the border between NC and SC across the street from Carowinds. I usually go here later in the evening and you don't have to wait for a pump, but during the day, I've driven by with lines that are 2-3 cars deep.
The location is convenient to I-77... I'm not a big fan of Carowinds Blvd since people seem to drive every where they want to and not follow the lines on the road, but that's just my side-issue.
