UPDATE: THEY SURVIVIED!

I was right when I figured they were ready to get off the trail.  Kevin and Eric hiked fast and furious so they could get to the truck one day earlier than planned!  As I write this they are in a McDonald's drive-thru ordering coke and fries, on their way to a Hilton in Knoxville.  They are giddy in anticipation of a SHOWER!  Tomorrow will be the best Father's Day!!
PS: They arrived! Nice beard, and can you tell who wore a hat and who didn't?
