I can do you one better, Bob--I lived next door to Muhammad Ali in the early 70s in Cherry Hill, NJ! Got to meet him and also a tour of his house. He was a real gentleman and not at all like his public personna.
I spent 2 weeks in his training camp in March 1975 when he fought Chuck Wepner-met him on an airplane 2 months earlier, and he invited me to camp, I came and never left. Hung with him every day.
