Charles Lipscomb asks "What is it about legs?", and respond "I don't know, but I sure know a lot of guys who got theirs torn up somehow". Heck - I am one, training accident, sort of. Blew out a knee on a field exercise (the one time in three years the whole division including the SJA Section went under canvas) as a JAG in1976. I think '76, maybe '75.
