Could a large convenience store chain known as the world’s largest gas station be coming to the Pennsylvania Turnpike? Buc-ee’s, which is a Texas-based chain, recently erected a billboard on the Pa., Turnpike sparking speculation, with its larger than life beaver mascot and 120-plus gas pumps, is heading north. Recently another such sign popped up along the New Jersey Turnpike as well. The billboard in Pa. is located between the Reading and Morgantown exits near in Lancaster County. On average, the stores are about 75,000 square-feet with at least 120 gas pumps.
