Matthew J.X. Malady in Slate:
The 4 hour and 46 minute drive from Philadelphia to Pittsburgh is marked by several things: barns, oddly timed roadwork projects, four tunnels that lend themselves to breath-holding competitions, turnpike rest stops featuring heat-lamped Sbarro slices and overly goopy Cinnabon. But perhaps the most noteworthy—and useful—hallmark of that road trip is all the bumper stickers that one spies along the way.
From Center City Philly to about Reamstown, it’s all Eagles and Phillies and Flyers stickers. Then there’s a 150-mile stretch of road where anything goes. Penn State paraphernalia, Jesus fish, and stickers about deer hunting mix with every other form of car commentary to create a hodgepodge that predominates until about Bedford. From there, it really is all Steelers stuff. And for those who make this drive fairly often, that bumper sticker progression serves as an old-school GPS. Of course, you’ll also spot stickers referencing cheesesteak lingo, as well as those emblazoned with “N’AT,” on this trip. And if you’re from out of state and decide to rest-stop query the owner of a car bearing one of those stickers, within the first few words of that person’s spoken response you’ll realize why linguists love the Keystone State.
