I was stunned and saddened by this news yesterday. I picked out my "favorites" and have been watching them closely since Sunday. And Bob was one of those, him being in the lead for the 50+. I couldn't help but sit here and be amazed and in awe of him and his accomplishments. I couldn't help but think how great it would be to do something as amazing as this when I'm over 50. It's a tragic thing, indeed.
