It scares me to think that I may know more about this topic then some guys out there. Me and my damn curiosity. Oh well... and by the way, for those of you that don't shave, or even trim, just remember this simple quote:
"If you want me to do my job right, I have to be able to see what I am doing" aka never dive head first into a jungle blind.
We want hair stuck in our throats or in our face just as little as you want it in yours. It is just a common courtesy.
