The Governor of South Carolina had an affair with a woman from Argentina. As his cover story he told everyone he was hiking the Appalachian Trail. To sum it up it is slang for having or having had sex.
"Hey have you seen Mark?"
"No but I heard he's with his girlfriend behind the bleachers. They're hiking the Appalachian Trail"**winks**
"Oh that dirty bastard."
Lakawanna Trail is a redneck shit show of a town in PA, about 30 mins from Scranton and 2 hours from Philadelphia. The locals have never produced any contribution to society. The high school kids are not even athletic. Overall the town is small and every cock in this area is about 2 inches. This place should be destroyed.
