Hiking the Appalachian Trail 

A poorly executed secret tryst - that isn't a secret to anyone.

It is a reference to the disappearance of South Carolina Governor Mark Sanford who "disappeared" for a week to Argentine on a romantic escapade. His staff and office told the news media that he was "hiking the Appalachian trail."

Dave needs to take a break from hiking the Appalachian trail with his secretary and get some work done!

hiking the appalachian 

In June, 2009, South Carolina governor Mark Sanford disappeared from public sight for five days, a period during which neither his wife nor much of his staff apparently knew where he had gone. A Sanford spokesperson eventually told reporters that the Governor was on a secretive hike along the Appalachian Trial to clear his head after a tough legislative session. Turns out that Sanford had actually been in Argentina where he had been conducting an extra-marital affair.

"Why is Bob's wife angry with him?"

"He got caught hiking the Appalachian, if you know what I mean."
