There is a really big smile on Sam's face. That's the best part of the picture even though you can't see it. He does not stay out long when he fishes. Usually 3 or 4 casts, he's done at the first fish or the 4th cast whichever comes first.
Sam had an unrelated umbilical cord blood transplant of stem cells to halt the progression of Metachromatic Leukodystrophy.
