A single example will serve to illustrate this. On Sunday morning, after getting within a short distance of the top of Cooper Spur, Bennett sheared an engine sprocket key while tearing over a particularly mean stretch of rocks. A search failed to produce a duplicate of the special design necessary for the particular sprocket and the boys finally devised a key from the tang of a file. This lacked the necessary strength for the rugged work it was called upon to do and, Walker finally volunteered to make the long trip down to Homestead Inn to get another key. It is doubtful if those who never have tried mountain climbing can appreciate just what that arduous task amounted to. There are any number of persons who find their strength insufficient to climb Cooper Spur from Homestead, even after a good night’s rest and, yet, Walker , after working all morning in the rarified atmosphere where every movement is an effort, immediately hot-footed it down and up again in the heat of a noonday sun! The Fox News cameraman still was waiting when he got back with the key.
