Once a year the kidney walk does a walk at the Philadelphia Zoo. I try and do the walk for my friend Joe, who had a failing kidney and was on dialysis 3x a week. Joe recently, this year about 6 months ago, got a kidney transplant. We were all so happy for him and that made this year's kidney walk so much more special. It felt great to be out there supporting a good cause. Joe actually just got accepted as a 2012 transplant olympics contestant, he was so excited!
