Over this weekend, area gas prices were in the $2.49 per gallon range. This extended from Mint Hill as far south as Westinghouse Boulevard (Exit 1 off I-77). Crossing the state line to Carowinds Blvd—just an eye blink away—gas prices were $2.29 per gallon. At the next exit, in Tega Cay, prices were in the mid $1.90s per gallon range. Even factoring in South Carolina’s less expensive gasoline tax, I still find myself wondering how just a handful of miles can equate to a .50 cents or more difference in gasoline prices.
