You may not feel outstandingly robust, but if you are an average-sized adult you will contain within your modest frame no less than 7 X 10^18 joules … - Bill Bryson

So I decided to do it [hike the Appalachian Trail]. More rashly, I announced my intention - told friends and neighbors, confidently informed my publisher, made it common knowledge among those who knew me. Then I bought some books... It required only a little light reading in adventure books and almost no imagination to envision circumstances in which I would find myself caught in a tightening circle of hunger-emboldened wolves, staggering and shredding clothes under an onslaught of pincered fire ants, or dumbly transfixed by the sight of enlivened undergrowth advancing towards me, like a torpedo through water, before being bowled backwards by a sofa-sized boar with cold beady eyes, a piercing squeal, and slaverous, chopping appetite for pink, plump, city-softened flesh.

I have long known that it is part of God’s plan for me to spend a little time with each of the most stupid people on earth, and Mary Ellen was proof that even in the Appalachian woods I would not be spared. It became evident from the first moment that she was a rarity.
