The most difficult thing I have ever done as a photographer was to follow Missy Koch into the operating room where she was facing the amputation of her leg.
We were friends before the surgery and have stayed that way in the ensuing three decades.
Missy's husband Todd Billingsley has written a book about Missy's life, Run to Win.
Last week, I talked with writer Josh McCauliffe about Missy, stirring up old emotions and remembering old stories.
