allthumbs Posted May 4, 2002 Share Posted May 4, 2002 Class 1: you fall, you're stupid. Class 2: you fall, you break your arm. Class 3: you fall, you break your leg. Class 4: you fall, you are almost dead (i.e., you can't breath and move your arms, legs, and head). Class 5: you fall, you are dead. Quote Link to comment Share on other sites More sharing options...
Greg_W Posted May 4, 2002 Share Posted May 4, 2002 Pick up a copy of Steve Roper's "Camp 4"; it has a lot of good history and does give the chronology of the YDS System. I think Dru is pretty close on his dates. Greg Quote Link to comment Share on other sites More sharing options...
