Long, unstable, hot, and crowded approaches! Hell...even I don't like those. Oh! I do recall a dog who got cut on some of those sharply broken talus chunks along the base of the "Upper Canopy" but he was a S.L. City dog not accustomed to the rigors of alpine four footed travel.
Winston Dog is originally from CO. I imagine his climbing experience prior to the Jungle was limited to walking around Rifle carrying a stickclip in his mouth and not erasing his tick marks. Clearly, he was unprepared for the Jungle and almost lost a leg.
