I only just saw this thread. Thank you Mike B., for posting that photo of Sir Boab, I think it really captures his persona and essence. The times I have been with Bob, I actually felt like those kids appear, welcome and under the wings of the great man.
I am the friend of another great man very similar to Bob in many ways and had the pleasure of introducing them on a golf trip to Wild Horse, and an evening of steaks and wine and wonderful conversation. They were both in Korea and had an instant sort of short hand set of phrases and sayings about those days and became quick friends. Bob had Steve out to the Shore Course later on. So, I just told my other friend (Steve the Marine Corps Major, Ret - same age as Bob) of the health news. His reply was "don't worry, he is one tough old soldier".
Huck, please IM me the address.
