I spoke with B Lance's buddy, he was a wealth of information.
Glad that helped you.he has had more surgeries than anyone i know- shoulders, knees, ankles- all multiple times. Even my buddy that played in the NFL for 10 yrs has less surgeries than he.
FWIW, chuck still gets around pretty good but his backpacking for sheep days are over- though I wouldn't put it past him to try....he is a tough SOB.
