There is one very prolific and excellent cave instructor which has been teaching for over 20 years,and he does something to teach his students a lesson. When leading a class he will deviate around the lips at Devil's and will enter the step down room. This room has no line,and he will turn around and give the thumbs up. Most students have been blindly following him,and didn't run a reel,now the exit out is not evident. There are many lessons being offered here,that resonate with the student in the future,but the main point is people will follow guides blindly,get in a bad situation,and unable to self rescue.
