I'm glad someone brought this subject up.
I've taught Hunter Ed. and IBEP for better than 25 yrs.
There are very few "hunters", that can show where the internal organs are positioned, correctly. Nor can they idenitify the sketal structure.
Its not that they aren't good hunters, they've been told to shoot behind the "point of the shoulder", by their mentors and hunting friends.
Most after taking an IBEP course have a better understanding of the internal organs and skeletal structure.
Its suprising just how many people have told me, after taking the IBEP course, that they learned the correct placement for the internal workings of a deer.
Not putting anyone down, its just they didn't have access to correct information.
