This was an odd blast from the past to see come up. Ironically, I was thinking of this lately due to both my fall on Wednesday and my still swollen and painful knee, and because something else made me think recently that I got lucky that day, as had I not put my sweater in my pack the impact of my fall in 2010 could have given me a pnuemothorax, if it didn't break a rib.
Take care, Mike.
