A favorite southern convenience store chain is teasing Pennsylvania drivers.

Buc-ee’s, the Texas-based chain known as the world’s largest gas station in the world, recently erected a cryptic billboard on the Pennsylvania Turnpike. Oddly, a similar billboard popped up along the New Jersey Turnpike several weeks ago.

The signs are sparking speculation the cult-favorite chain with its brisket sandwiches, larger-than-life beaver mascot and 120-plus gas pumps is heading north.
